Hope these tips and ideas helped. Can't wait to see some designs people come up with.

another option for "harder" coat is to have it painted using paint gun. The paint gun allows to use acrylic hardener, exactly like in professional coat in cars etc. it is impossible to add hardener to a spray can - the can content would turn into solid in hours.

cheapest compromise: make base and color using spray cans, and then take the frame for coating to car painting shop.

spraying over powder coating has one more advantage: powder coats are limited to RAL color palette (at least in Poland). you can fill cans (for spray or gun) with every car color possible or have a custom color, with pearl and metalic gloss.

Awesome paint, great write up. The guide is right: pick warm, dry, still weather. I've sprayed in cold, humid, windy conditions and won't do it again. One thing I didn't see in the guide was the reminder that spray can coats typically do not have the hardness of a decent powder coat. I've tried engine enamel (supposed to be harder and more resistant than, say, regular lacquers) with professional urethane coating on top, and it still chips far easier than powder coat. Again: great job on this post!

Powder coat? What's that? Is it comparable to the bike manufacturer's paint? I want to change the look of my new bike. I mean, who needs to ride around on an aluminum advertisement? But the question is, will the new paint job weaken my bike? Could I paint over the original stuff to keep the same amount of protection? Maybe I should slick with stickers.

Powder coat is a type of paint; I believe that it is what all bike manufacturers use.You will NOT be able to replicate this; basically, a statically charged powder is sprayed onto the frame, then thrown in an oven to bake.
in other words you would have very little success replicating this at home, I would suggest not even thinking about it :/

If your frame is aluminum it will be fine with or without paint. If it is steel you want to keep all the bare metal covered to prevent rust. DIY paint jobs will chip easier so you will need to retouch from time to time.
i second the dry, warm and still weather policy. 2 years ago when respraying my motorbike i had hell of a time picking still days. Living by the coast is a killer for me. For steel i spend forever getting the surface cleaned up and degreased, A few layers of primer, many coats of paint and then a few coats of clear lacquer. Unfortunately for my mobike i forgot to use petrol resistant lacquer. For alu, stripdown to the metal and plenty of polishing. Remember, LOTS of THIN coats.

Give Rustoleum Appliance Epoxy paint a try.
I use it on anything metal, it bond better than most paints and hold up to beatings.  I sprayed a Jeep frame and axles and suspension parts, and they held up great to offroad abuse.

Remember like most things the key is prep.

If you want black, use a product called POR-15 then cover it with their chassis black.  It needs no primes and can be put on straight over bare metal as it's a rust preventer.  This would be perfect for a mountain bike.

I've also sanded the stock paint to give it texture then sprayed it with various liners. (Rhinoliner, Line-x, etc.)  My favorite is Raptor liner it's tintable and can be matched to your paint.

Great Bike! I just attempted my first rattlecan job, and like you used Rusto products. However when I put my clear coat on the paint started to crackle in some areas and not in others. Did you experience that at all?
 the paints are curing at different speeds. The clear is drying and shrinking therefore it is cracking. sounds like a lacquer on enamel. enamel takes a long time to cure.. days, I would probably let it sit for a week before I put anything on top of it.

I've had that happen on some wood furniture I was painting. Basically you should wait extra long between the last color coat and the clear. Also remember to use thin even coats. To much clear on 'not quite dry' paint is what causes the color to separate and crackle. Sometimes that can look cool though.

I have an old bike that has been stored away for a long time. The bike frame needs to repainted,and the rust taken off. It seems the rust might be heavy(maybe) When I go and srtip paint,what do I do with the rust? What type of sandpaper do i USE,and how do I treat the rust before I prime it.
 Get some Naval Jelly from your local hardware store and brush it on the heavily rusted spots. Your still going to have to sand it with some low grit paper to smooth it out but Naval Jelly will get rid of the rust. Use whatever grit you need. I would use paint stripper first on the whole bike and then hit it with some 150/200 to rough it up good. Wipe it down with wax and grease remover. Then use a tack cloth to grab anything extra and PRIME!
This was a nice instructable and I just repainted my bike. Stripping was definitely not an easy job but I did paint my bike two colors. It took quite awhile overall but I was happy with my results .... until I noticed that when I set my bike up outside against a wood post, it totally chipped this huge line across one of the main tubes of my bike. It looked nice but now it seems like a gust of wind will take off the paint. I added quite a bit of clear coat too which didn't really seem to help out at all. Used rustoleum paint as recommended. I am going to hate touching up like once every month so is there anything else I can add to make a protective layering?
I think you used an acrylic lacquer over an enamel finish. Enamel paint never actually "dries" (enamel is oil based, it will cure to a certain hardness but that is it). This means that the lacquer clear will create a hard shell on top of a malleable/soft layer of paint. Think of Skittles..

Either that or you simply didn't let your paint coat dry before you put the clear on.

Sorry buddy, but your best bet is to strip it down and repaint again. I wouldn't add anymore paint layers to it. 

I would use dupli color acrylic lacquer paint. 
use krylon fusion and make sure you strip it well pm with your results
use a spray polyurethane. It also sounds like there was a problem durring prep. I use Valspar and Krylon. (Lowe's) . i always suggest alleast 1 week "sitting" time after painting for the paint to completely harden. Also remember that cold weather can cause paint to dry slower... always paint between 60 and 95 degrees. also you can try drying in the sun...
I never thought to put plaid on a bike. I repainted two bikes, and am in the process of painting another. The one that I'm riding has a really crappy paint job, which is due to the fact that I used whatever sandpaper that was lying around the house, and painted with whatever paint was yellow. But after reading this, I just might strip it down again and paint it like that. Thank you!

i'm painting my bike and it seems that after the priming, the surface is rejecting the paint. the surface being handlebars and paint being rustoleum metallic gold, it just wrinkled up like foil almost. does anyone know what that means and or how to fix it?

For those interested in Powdercoating, go to www.eastwoodco.com they sell powdercoating kits,and supplies. Its very possible to powdercoat at home, it just takes time,and some investment.

A bike shop owner once told me that appliance paint, like for refrigerators, was the best thing for DIY bike painting. Haven't tried it myself so I can't vouch for it.
bellos diseños! también puedes probar con vinilo autoadhesivo. saludos!
