Ok, other than just sand and bondo...is there a "How To" out there to prep for paint the correct way? Any little tricks of the trade to help me out? What grit paper do I use for the final smooth sand? This is one area I know NOTHING about.

I have some Lariat flares I need to prep for paint. Any help guys?

 

i think the prep guys at work use 220 or 320 last before painting
