This is more of account of how I got rid of/ hidden/ covered up the rust on a 1996 Toyota Camry. The rust was around the wheel wells on both of the rear wheel wells.
This is the first time I have done anything like this. I have never used Bondo, I have removed rust and some minor metal working before but nothing like this.
There was a total of 20 man hours or so working on this.
All the car experts are probably going to say I didn't do so and so right or so and so. You can give me encouraging comments and pointers and I will remember them the next time I do it.
intoon has a good Instructable I have read through I recommend that you do too.
I am entering this into the Metals Contest so please vote for me.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials/Tools
You need quite a bit of things for this task:
First of all you need the car you are working on.
A work space is necessary, I did it in a two car garage so I had space on each side of the car. If you did it outside, you would have to make some walls for when you paint that nothing gets on the paint job.
Dremel(with multiple bits)
A grinder would really help(which I didn't)
Sandpaper(a lot of different types)
Good lighting( a couple different lamps)
Cleaning agent(i just used water)
Bondo(mine came with a little spreader)
Place to mix it
Wire Mesh(my Bondo came with a little but I also got some at the same place i got the Bondo)
Paint to match your Car
Oh and a nice stool, soft blanket or knee savers are very helpful because I did a lot of sitting on the floor and those really helped.
Step 2: Starting-Remove Rust
Just sit down and start removing rust.
First I picked at all the paint and took off all the paint that came off easily and than removed the paint about a quarter of an inch all around the rust spot.
You can use:
Dremel with grinding wheel and steel wire brush
Or a grinder with a sandblaster wheel
Just keep going at it. This part takes a long time to do and is really annoying.
You have to do this right or the rust will come back.
Cut off the big pieces that are rusted through.
Step 3: Rust Gone + Wire Mesh
Keep taking off the big chunks than take off the surface rust.
All we want to see is sheet metal.
Make sure to wear a face mast, rust dust and metal dusk is harmful.
Sorry some of these pictures have take and newspaper in them, i coated the inside with a black paint that prevents rust from coming up. The paint was almost like truck bed lining.
Once you have all the rust gone, add the wire mesh to anyplace you took big chunks on metal out so the bondo has something to attach to. (Pic. 9 and on)My wire mesh was sticky on one side so i had to flip it over and stick it to the inside of the metal. My wire mesh also was easily cut by scissors so cut to to what ever shape you need. Try to fallow the curvature of the vehicle. Look up pictures of the car online if you need to get and idea.
Step 4: Bondo...
Now comes the fun part! BONDO.
Make the bondo per how the container says to.
Add more where you cut out big chunks, and where there was surface rust not so much bondo.
Apply more Bondo.
Apply more Bondo if needed.
When first sanding the bondo, start with rough sandpaper, than as you get to almost done, switch to a softer sandpaper to make it smooth.
Like before, you want it to match the curvature of the car.
This is where you really need to wear a face mask, gas mask, the little bondo particles get everywhere! If you are sanding you could set up a shop vac to up the dust right away.
Step 5: Get Ready for Painting
Once you have the Bondo sanded exactly how you want it, and remember once you paint its hard to go back without a lot of time and effort (and possibly starting this Instructable over again), you are ready to get ready for paint.
1. Use an air compresser with about 40-60 psi and spray down anything within 3 feet of where you are painting to remove the dust and stuff.
2. Clean up the area or get the vehicle in a paint booth.
3. Start taping newspaper everywhere, i did basically anything within 3 or 4 feet on the car. Tape it tight to the vehicle. Even put newspaper on the wheels.
4. Put a lot of tape around the areas you want painted, I tryed for about 3 or 4 layers going up around it.
5. Shut the garage door or the paint booth because you don't want a breeze moving dust on the paint.
Step 6: Prime+Paint+Clear Coat
All you have to do is fallow the instructions on the paint container.
First prime, I think I did 2 or 3 coats of primer.
Second paint, I think I did 3 or 4 coats of paint. Make sure you get a paint that matches the vehicle's color. You should be able to find that out on the internet.
Third clear coat, I did 2 coats of clear coat.
*Make sure no one walks by them while drying and touches them.
**Make sure you allow adequate drying time between each step and each coat based on what the paint containers tell you.
***WEAR A MASK WHILE PAINTING! PAINT FUMES DANGEROUS!!!
Right before I went to paint or prime, i opened the garage a little to allow some of the fumes to escape and get oxygen in there.
Step 7: Admire
Take off the tape and newspaper.
Pull the car into the sunlight and admire.
Buffing and waxing is a good idea too.
Step 8: After Winter
Winter took a hard tole on it. Some of the rust is coming back and showing through the bondo. So I am going to have to do it again.
To add onto that, someone was pulling out of the parking space next to the car in a high-school parking lot and made a small dent where the bondo was/is on one side and scratched black lines down the back end. So I might update this Instructable when I fix that or make a new one.
