...if a feller had the patience and correctly prepped everything, would a rattle-can paint job last any amount of time? I also want to make it clear that I'M NOT PLANNING ON DOIN THIS TO MY LS1 CAR, I'm considering the possibility for my beater.

 

I've always wanted to Rhino Line the outside of a car.

 

dont think you can do it with rattle can. ^^^thats some funny *** **** right there or hell go the hydro graphics route.

 

Should hold up for a few years if you clear it as well.

Never tried it though..

Get a cheap paint gun and the cheapest _automotive_ paint you can get your hands on, and it should last a lot longer though.
Shouldn't be more than a couple of hundred in total, and you'll get the benefit of learning something in the process.

 

i flat blacked my beater, i usually have to throw one coat on per year cuz it fads a little(i got the cheapest crap). this is with no clear coat of course so if you did put a clear on, it would probably last a few years if you prepped the surface correctly. sanding, degreasing, etc....
