My new roller frame

[Jbm1956]

Well ive been messing with my lowered axle and lowered leafs for quite some time now. Well day before yesterday I was on craigslist (due to my daughter waking me up at the butt crack of dawn) lol. Well good thing she did I came across a 55-59 chevy frame with a camaro clip installed with new bushings a camaro rearend under it and an aluminum fuel tank. I know you guys aren't going to believe this but I got it for $500 bucks. Awesome deal I think. So my question is im all excited to get it going it has some nice paint on it now but the whole frame isnt painted. So I want to spray some fresh paint over it. Can I just get some paint and spray it or do I have to get rid of all the paint thats on it already. Im hoping spray some on it and then run my brake lines. Please point me in the right direction. Thanks guys
