well I had the perfect minibike test parts to try this 2k urethane(2 part mix in a can) project.
bike is going to be use for flat tracking so I really don't need or want the frame to look good or need a high quality paint job on it. frame can stay a semi gloss black out of a spray can for the most part. running on clay at the end of the night does not make it look pretty or make it go fast.....lol, but the tank is a different story. I need it to hold up against gas leaks or spills. so for only $24 dollars I fix that problem and did not cost me ton of money like it normally does when purchasing automotive paint products.
so what i did first was sprayed the tank with the semi gloss black and then let it dry for couple hours. then installed the decals and then a light coat of clear. let that tack up for little bit and then gave it three full coats of the 2k urethane(2 part mix in a can) letting it tack up between coats.
paint job came out so smooth I won't have to do anything to it. just bolt it up to the
bike and go.
