Can I get any durable spray paint in an aerosol can?

I painted a bicycle with Rustoleum. It looked beautiful at first, but it ended up looking awful before long. You could practically scrape the stuff off with your fingernail. Is there anything out there that would be tougher?Can I get any durable spray paint in an aerosol can?
concordbridge is right, except for one thing, washing your bike wont be enough for adhesion. You have to sand it.





It's a good idea to clean the surface, but sanding is the only thing which will guarantee proper adhesion. I would suggest a fine grit sand paper (180 to 280 grit) so you don't sand through the original finish, and the sanding scratches don't show through the spray finish.





I don't care what it says on the paint label, sanding is necessary. The only reason they don't say so is because people hate sanding, so if they actually said that you have to sand, fewer people would buy their product.Can I get any durable spray paint in an aerosol can?
Dear Reality,





I've not had real good experience with Rustoleum.





The absolute best spray paint I've used so far, and also one of the least expensive, is Krylon.





Most home supply stores carry it. Krylon also makes a water-based spray paint, but it is not as durable.





You need to make sure that the surface you are spraying it onto, is in good shape. Sand it a little, and definitely clean it well.
I think I know the problem. I have done the same thing.





Paint has two jobs to do:


1) Provide a tough, impermeable coating


2) Adhere to the surface underneath.





Only one is completely in your control.


The chemistry majors at the paint manufacturers have done a good job of licking the first problem, except when the EPA changed all the solvent regulations for auto paint in the early 1990s.





I suspect that you didn't do a good enough job on the surface prep.





Now you are going to have to remove all the bad paint as well as the prep the surface under it. Next time start with a pressure wash from one of those coin operated car wash places. You can even clean greasy engines with them.

i will answer your like you answered mine, just don't eat it. or better yet, learn how to prep better. only doing a half way prep, you ended up with same finish
