quality spraycan paint?

I painted my motorcycle's 'tins' flat black out of a spray can. I then sprayed several coats of a matte clear coat finish. This is holding up well on the fenders. But any time I splash gas on the tank, it messes up the paint and I have to touch it up. Is there any brand of spray paint in a can that will withstand gas spillage?

no, there isn't. spray can paint does not have the hardeners to withstand gas. just have to be real careful or put a bib on (that's what I did...)

I haven't tried it yet but on another forum the guys swear by John Deere Blitz Black (pretty sure you can only get it from john deere). Apparantly its some pretty tough stuff since its made for use on farm equipment. Like I said I haven't tried it yet though.

How much gas do you spill on it? I just used some el cheepo flat black stuff and haven't had any problems with mine. If I get a little on it I wipe it off with the paper towels at the gas station and Haven't had any problems. I didn't even put any clear coat on just 4 coats of paint ontop of a primer. I thought I would have problems but suprisingly havent.

I'm not a painter, but I have done a number of homespun paint jobs. There are basically 3 types of paint currently in use. Acrylic lacquer, acrylic enamel, and polyurethane, or catalyzed enamel. Only acrylic lacquer and acrylic enamel are available in spray cans. Lacquer is totally unsuitable for motorcycle use, gas, and many other solvents, like WD40, will wash it right off. You can get a beautiful finish with lacquer, but it just won't hold up. Acrylic enamel, like Krylon and Rust-O-leum, in GLOSS colors holds up fairly well. It will give you a more "industrial" type finish, and takes a lot longer to dry, or "cure", but it is what I would use on a motorcycle if I were going to paint it with a spray can. "Baked enamel" is what was mainly used before polyurethane enamel came along, and it held up pretty well. Flat, or matte paints simply don't hold up well no matter what. They are more like primers than paint. If you want a matte or satin finish, powder coating is the way to go.


Polyurethane enamels should only be used by professionals. They are not cheap, and require some degree of skill to do a good job with. They are also dangerous without the right equipment, they use cyanoacrylate as a catalyst, or hardener, and that stuff will rip your lungs out without the proper breathing protection. If I am not mistaken, DuPont Imron was the first of this type of paint. HOK and PPG make all different types of it, but as far as I know, it is not available in a spray can, because the ingredients have to be mixed just prior to spraying. Jerry.

say these words

"Acrylic Urathane's".

That is what todays paints are.

Duponts "Imron" went out the window years ago. No one uses it anymore. Which is sad, really, because they invented it, and then sat back and watched the rest of the manufacturers run circles around them.

PPG, Sikkens, make the best, IMHO, for whats thats worth. Sikkens led the way, everyone else followed suite. Overpriced stuff, thats forsure. I like PPG personally.



The stuff is not in a spray can, nor will it ever be.

There is no single buy it at Walmart,Autozone, Napa, Pohdunk Auto Supply store paint that will hold up to gas. NONE....If it doesnt have a catalyst, it wont, will not, will never, ever, hold up to you spilling gas on a tank. Ask the salesman if they will stand behind it when you bring them a gas tank that looks like you smeared wet paint on it, dulled into next week and more or less ruined, if they'll stand behind the gas eating it warranty, which there is no such thing.

So, paint the rest of your bike with whatever, but if ya spill gas on it, its gonna eat it, big time...

anybody tells ya different, the're lying....or ignorant, or gullable...


and isocyonates will so screw up your nervous system, your doctor will have to explain it to ya. Etching primers have sulpheric acid and othe good stuff in it. Paint is a chemistry lesson kids....

All those great chemicals in paint is why some are switching to waterbased paints now. supposed to be good stuff I guess but I'm not a painter by anymeans. would love to do body work but can't stand the sanding and prep work. and we all know the prep work is what makes the difference between a good paint job and a great paint job.

I'm sure my paint will have issues with gas eventually, like I said I expected to have them thats why its cheap. I don't ride the bike much so I don't fill it up too often which cuts down on my chances to spill all over it, but we all know it will happen sooner or later

I've cut this special rubber 'blanket' with a whole in it. I just need to make sure that I fit it on right so that it does its job.

look on your local craigslist for a powder coater, most of the time you can get stuff done very cheaply, and it will outlast the bike. my tank and fenders were done with vht gas resistant and its already faded after 4 months, that was with a complete strip, and primer.
I found a powdercoater and im prepping the stuff, doing tank and fenders jet black, and chain guard and fender braces black chrome. its going to be 100 ish bucks.

I know of one guy who bought a used oven at a garage sale and used it to powder coat some tins. Just remember the oven has to be big enough for the stuff to fit!

While do it yourself powdercoating is certainly possible, unless I was going to do a whole lot of it, I would just have it professionally done. I would like to have my tank and fenders done in gloss black, and have the rims (just the rims, not the spokes) done in gloss red, then use a wide whitewall rear tire. The "Rat Rod" look, but done right. But that would mean taking the wheels apart and putting them back together, and I just don't have the time for that now. Jerry.
