Paint Prep

[1990_LX]

Can any of you guys give me tips on paint prep? I'm using my electric sander with 80 grit to get rid of the cheap Maaco paint job that was done, then I'm going to move up grits and block the rest. What grit should I go up to before primer? I was looking at cheap guns at Harbor Freight and was wondering if they would be okay for spraying primer. What do you guys think? Any input is appreciated!

Go up to 300 grit before priming, and up to 600-700 before basecoat. Be careful with the electric sander that you dont leave high & low spots. Your better off using an compressed air DA

Well I don't have a DA and I'm not sure if my compressor would handle it...what about just blocking the whole thing?

No need to tell me! ha Since I already used the electric sander on it will primer fix the highs and lows?

Depends how deep you went with it. Throw a coat of primer on it and check it out. You can build up primer pretty thick so if you didnt burn it too bad then yes you should be able to fix it. Just remember to paint lots of very thin coats instead of a couple thick coats.
