What does BONDO short strand fiberglass body filler NOT stick to?

I'm thinking of building a small canoe by making a cheap mold and spreading the fiberglass stuff on it and popping it out. However, it is sticky. Anyone know what the stuff DOES NOT stick to. And perhaps and ideas on making a mold.

Help with a cast metal coin instructable!

Need help finding a particular instructable, friends.  I would almost bet body parts that I saw an instructable here that had the following process to it for making a custom fantasy coin or medallion: Use the underside  bottom of a paper coffee cup-mix up a portion of Bondo and fill the bottom recess with it.  When Bondo hardens, pop out the round disc, paste a paper disc onto it then draw out your coin or medallion design.  Carve out your design with a dremel or similar, make a silicone putty mold, then when mold is dry, pour pewter or zinc to make a custom coin. Darken and polish. I know I've seen it, I'm wanting to stick it in my favorites list so I don't lose it again, and I especially want to thank the author for coming up with such a simple process for a custom medallion. Can anyone help me?

Is a helmet lighter when made with a plastic cast mix or a resin mix?

See, I am making an airsoft helmet and I wanted to know if using a plastic cast mix (such as the Smooth-on brand) would be lighter than a resin mix (such as fiberglass resin and Aqua Resin). Please give me an answer and/or links to find out more.

The Ice King's Crown

It's my take on the Ice King's crown. For the "gold" part, I first tried gluing plastic paint buckets together, but they were too thin. I ended up covering the outside of one bucket in Bondo and then cutting in the peaks with a jeweler's saw. For the jewels, I cut a positive mold for each one out of a scrap of cutting board, then pressed them into clay to make a negative mold. Then I mixed up some casting resin and red dye and cast the jewels. They were epoxied onto the crown before I locked them in with Bondo bezels. If I were to do it again, I would use a more acute conic shape and make the peaks taller. I might also use fiberglass-reinforced Bondo and try a different gold paint. If I'm real adventurous I'll cast the thing out of scrap aluminum.

Deadmau5 head with plastic / wood / fiberglass ears? Do I need to mold them using body filler and glass fiber?

I'm going to use deadmau5's cheese head as it is visibly the best for an example. The ears are made of a hardened material with a gloss finish. The holes through them seem to clearly show that they are not foam underneath. I was curious as to how I could achieve the same effect and strength. I've seem some exquisite models of helmets here and in particular individuals who have created the daft punk helmets. They created molds. I've never used fiberglass / body filler / etc but I'm a rapid learner and I'm willing to suffer trial and error like anyone else. I was curious though, if it is possible to take the styrofoam ear and then coat the ear with bondo (or another body filler/putty) to create that hardened mold and then primer, paint and gloss it. Can someone with experience with these materials shed some light. I really want to achieve this look! Here is a video of the cheese head when it was unveiled: Thanks in advance guys. I can be contacted via email at "sip_deco_c@hotmail.com" if required. Help would be greatly appreciated! Peace, Deco

My Costume Picture Entry

So I was hanging out with some buddies of mine in my spartan costume...betcha can't guess which one is me. My costume consists of: Helmet - Cardboard shape, covered in bondo and spraypainted. Bicycle helmey pads inside. Shield - Cut plywood, with a cardboard lambda, covered in bondo and spraypainted. Polyester straps are riveted/gorilla glued on the back. Cape - Scarlet cotton fabric with polyester straps to keep it from choking me. Beard/abs - Mom's eyebrow pencil...If you have experience with spirit gum, use that and fake hair, unfortunately, it didn't cooperate with me. Pantalones - If you're feeling frisky, wear a speedo, if not, brown shorts are acceptable

Plastic containers that have #2 on bottom. Who knows of a bonding agent?

I have tried several different rods with my plastics welder, super glue, two part epoxy and bondo. Something to bond #5 plastic containers would be helpful.

Daft Punk helmet from baseball helmet

Hi everyone! So I read and reread many threads and have a few questions about a building a Daft Punk helmet for hallowe'en. Now I know all of you are probably saying "pfffft not another one" But mine will be different and you will see once it is done. It is more of a Daft Punk Inspired helmet. Anyways, the helmet will be Thomas's helmet which will be started from a low profile rawlings baseball helmet. But will have a few changes to it from the original ones. My question is: After applying the bondo onto the helmet, to strengthen the inside, do I use bondo again? spray foam? or nothing since the baseball helmet is basically still there. Thanks! And I will post photos of progress. Antoine

Game pieces for life size Operation game

This is for a halloween carnival and will be used over and over again, so I would like for it to be fairly sturdy.  I thought of cutting insulating foam and using it, but it would probably break easily.  Other ideas I have had: bondo plastic styrene sheeting (yard sign material) cardboard plastic dip (dip foam pieces in it?) great stuff foam I would like for the pieces to be white, fairly sturdy, about 1" thick or so.  Nothing is jumping out at me as inexpensive and durable. Thanks for any help!

Help with costume

I'm making a costume that looks like this- This is actually my profile image. I have lots of corrugated carboard (but no large pieces yet-just medium sized boxes), thin cardboard, foamboard, and a sheet or two of lexan/plexiglass (for the green spikes), and I think I can get some fiberglass, resin, and some bondo. Does anybody have any advice on bending, cutting, dying(lexan-all I've got is clear) the cardboard, foamboard, or lexan? I've also never worked with fiberglass before-all I've heard is that it's a mess. Any tips? If anyone can help me with the head, antenna, armor, or especially the chest, I'd greatly apreciate it.

alternatives to fiberglass

Hey guys im building an enclosed recumbent motorcycle and i am a bit stuck. im making the outer skin. to get a working aerodynamic shape, complex curves and all i want to use some flexible sheet which i can connect to the strong points of the motorcycle. i am thinking of using that polypropilene chicken wire, and i wonder if it would be good enough to be the base of the fairing and put fibreglass on top. my brother wants to use cedar strips as a base and cardboard strips mounted over them and fibreglass the resultant mess. then bondo the lot. any ideas. i am not describing this very well. a single sheet of a flexible matting will save me the trouble of making a mould of the fairing. thanks guys.

How to Construct a GUY Daft Punk Helmet?

Hey guys, I was wondering how you would build a GUY Daft Punk helmet out of a motorcycle helmet. I have purchased a really nice motorcycle helmet for $30 and I started last night to make an outline of the golden frame that surrounds the helmet. I was planning on making this out of cardboard, and then after measuring it to make sure it fits the helmet precisely, covering it with Bondo. Once that was done, I was going to construct the plastic visor, which is where the trouble comes in. Does anyone have any suggestions on how that visor can be made? I have no idea how to do vacuum form, which is unfortunate. Any answers would be appreciated. Thank you.

Reshaping Rondo'ed pepakura items? Answered

I've done some digging, and I keep getting mixed answers on this. I have a pepakura helmet I have been working on, and recently, I had the back end of it warp on me. I applied rondo (which is roughly 70% figerglass and 30% bondo) It warped while I had it sitting in my car on a rather hot day, so my hopes for fixing it are high.  However, I have already taken a heat gun to it (which did make it very flexible) to reshape it. However, it always returns back to it's original misshaped form. Am I just no applying enough heat to it? Or have I basically accidentally created a memory material? Thanks in advance!

Joystick stickshift

I have been using a joystick stickshift in my sports cars for years. Just recently i was asked to share how to do it.  A joystick from a computer aracde game can be hooked up to your stickshift to allow you to honk your horn, wash your windows, pop your doors, change radio stations, dim your lights or a number of other  neat things. I am new to this group so I am not sure about how to do stuff on here so bear  with me. Find a joystick that has enough buttons to do what you want it to do, dis assemble the joystick, isolate the different switching circuits, solder new leads, route thru to a relay board,  wrap the stickshift lever with blue painter's tape,bondo the  shaft of the stickshift to one half of the joystick case, pull stickshift lever free and re do on the other joystick handle.   The relay board  allows the small circuit capacity of the joystick to operate higher circuit loads.  Joy sticks will handle 1 amp max load thru their contacts.

Recycle old spring horse into rocking horse....is bracing needed or what?

The childs weight and energy on a spring horse is spread out by the springs. I want to put wooden rockers on a spring horse and remove the springs etc. Would the horse collapse under the child ? How would I brace up the inside of the horse ? How would I attach the hollow plastic feet to the wooden rocker? I have cut off the mane and tail to put in a real horse mane and tail so I do have limited access to the inside of the horse. I have thought to line the inside with bondo /fibreglass and maybe fill the feet but I do not like that it is a not a green product and could off gas harmful components etc. Any suggestions would be appreciated. These spring horses were on the way to the dump so I was given them for free and wish to do something really neat with them. I have some glass elk eyes to insert and wish to make a leather saddle and bridle. Fun Times! Thanks for any help.

Idea: drive your paper dream car!

Here's an idea I had but realistically won't have time to work on. Okay, so there are these things called kit cars that have been around for years.  Basic idea being, you put a cooler looking body on your regular everyday car.  Neat idea but even the cheap ones start about 3 grand!  That's a lot of money for a raw chunk of fiberglass to add to car not worth half that.  Also there are other disappointments like: good luck getting the exact design you want that just happens to fit your make/model. Now in seemingly unrelated news these cosplay people have figured out how to (ab)use some software called pepakura to print out life-sized paper models of swords and armor and stuff.  Then to make them useable they fiberglass them, bondo and paint... HEY!  WAIT A MINUTE!  That's all car autobody stuff! You see where I'm going with this. Thus, therefore, and in conclusion my suggestion is that you do the following: 1) Watch "The Hero Tutorials" on youtube.  Pretty much the definitive guide for the paper cosplay thing. 2) Print out a lifesize copy of the batmobile or whatever and tape it to your car. 3) Do the autobody thing for tedious weeks on end. 4) Post an instructable in a contest I'm entered in and swipe the prize right from under my nose. 5) I feel sad at having become the instrument of my own undoing... yet console myself over the fact that the net awesomeness of the universe has increased significantly.
