if you really want to paint it yourself then i would definitely recommend doing it. but if you really want a sweet, high quality paint job, then i would look into a local painter/powdercoater.

i painted a frame once, and after i spent all the money on stripper, sanding equipment, primer, paint and clearcoat it ended up being pretty expensive. now i have a very chipped up frame. it was a good experience, but i wish i would have just paid the ~$100 to get it powdercoated.

Get Montana spraypaint. Be sure to sand.

Check the Classic and Vintage forum for paint threads, too.

If you go to the local powder coater, make sure you and he are clear on what sort of prep. is to be done to the frame. Some cheap powdercoat jobs are that way because the frame isn't completely free of rust/dirt/dust and the paint starts bubbling and popping off.

But powdercoat is the way to go if you want a single color, durable finish on the cheap.

Rattlecan can produce some good results but it takes some effort and time. $100-$150 to a powdercoater is not a bad deal at all.

I actually just finished painting my frame last week. Prepare to spend quite a while on it if you wish to have a nice look. Make sure you sand off everything (the paint and rust) and fill in dents or braze-on holes will bondo before applying primer (primer is a must). The primer type needs to match the type of paint you'll be using if you want a nice bond. PM me if you want more details.

Like others before have said, it's a good experience to paint it yourself, but if you want a decent and durable job, get it powdercoated. I just went to get my frame powdercoated for $75 yesterday and turn around time is 2-3 days.
If you are going to do it yourself, my best advice is to: 1. Apply nice even thin coats. 2. Don't spray the frame initially when you press the nozzle, rather start your spray away and then stroke over the frame. Doing it this way will avoid any "globs of paint", heavy paint spots in the initial hit area and prevent run offs. 3. I'd recommend getting a good primer & paint as well, there's local auto paint shops you can go to and pick out just about any color from Dupont or PPG and they can put it in a can for you.

I've painted a bunch of bikes and my motorcycle. I have some tips/advice.

1.) Prep work. Sand, sand, sand. Work up to a lighter grit like 600.
2.) Wet sanding. Breathing in paint is bad.
3.) Degrease/clean like a OCD Meth addict. One dirty fingerprint can cause the paint to not stick.
4.) Take time. Don't expect to do it in one sitting.

As for paint... you can get a killer job with rattlecans.

For a finish that will really look nice, I use the following method (haven't done a pedal bike, only an old Triumph chopper).

1. Do all of the above.
2. Primer.
3. Look for imperfections, like any fiber or dust trapped in the paint. Sand down bad spots and repeat.
3. Base coat of black spraypaint. Couple layers. You can wet-sand with a very high grit to smooth out, like 800 or so.
4. Spray a couple layers of Duplicolor Metal Specks paint. Make sure to clean the nozzle every 30 seconds or so, put the nozzle in thinner after clearing it when done with a coat of paint.
5. Spray 5+ coats of Duplicolor clear-coat.
6. Wait a month.
7. Wet sand with 2000 grit, then buff with rubbing compound, then wax.

Here is a nice spray-bomb example (not mine, I'll try to get some of my pics up later, and maybe do a tutorial on a pedal-bike).



You can get this same type of finish on a pedal bike for like 40 bucks, if you are patient enough and do proper prep work.

2x$10 duplicolor metal specks paint, $3 primer, $3 black gloss, 2x$7 clear coat.

If anyone is interested in a tutorial with pictures, let me know.

Exactly. If you really want to do it yourself, do it proper, but it will never last as long as a real paint job. I'm as broke they come, and I'm still gonna pay to have it powdercoated. You'll be happier in the long run.

I prepped my bike for paint. Degreased, sanded, sanded, degreased and sanded again. Finall coated with acid primer. Came to my senses and gave to pro to finish. First thing he did was bead blast it to remove the rust that sanding just cannot do. All my sanding and primer was for nothing.
Bottom line, I was about to spend about $100 on materials (not counting quality breathing mask). A local body shop offered to do it for $125-150, then I found a guy who only paints bike.s He did it for $195 including decals under clear coat. Spent a bit more, but got a fabulous metallic finish.
Re: powdercoat: I'll leave powdercoat for outdoor furniture, window systems., metal roofing... Powdercoat on a bike has zero appeal for me, has no bling or sparkle. It's an incredibly STRONG, but very dull looking Finish.
Also, the painting process is awful for the environment and your lungs. Let a pro do it. Hopefully they'll take care in the process.

I'm sure others will be quick to disagree, but in my experience, I've had the best results by NOT stripping/sanding off all of the original paint. Sand off the clearcoat, and use a high/fine grit (600 will do) on the entire bike so that the original paint looks kind of ****ty and faded. Then paint light coats, waiting for each coat to completely dry in between recoats. I like to wait a 2 days at the least between coats. Do a 600 grit sand on each coat after it has completely dried (not sure if it has dried? press your finger nail into it, and if it leaves an imprint, the paint is too soft and still wet underneath). Two or three coats of color, and another couple of clear. I did this to a carbon fork, and after over a year, there is not a single chip in it. Maybe it was just luck?
