First time painter shoping list?

You need a compressor and air dryer and gun with filter and adjustable pressure controll (you are not trying to paint custum just make it look better go to harbor frieght and craigslist but a good compressor is always important for many things). Next a air mask that can handle organic vapors and eye protection. You will need acetone and cleaning supplies. You will need surface prep tools sanders sand paper etc. Masking material to protect other things not wanted that color or painted. Then once prep is all done get a epoxy primer and then some filler primer to sand out imperfections in jambs and bay who cares about floor boards it gets covered. Oh dont forget seam sealer and body plugs if they are bad. Then focus on paint a simple singlestage and clear or base clear system the color of the rest of the car. No need to clear the floor boards just door jambs and maybe underhood. Thats my 2 cents and very general advise. Prep is important!! have fun
