QUOTE(7TPorsh @ Apr 29 2013, 09:37 AM)  Paint should go on to a smooth finish...I sanded with 1200 then shot with paint...then finish sanded to 3000 grit; then machine polished 2 stages. I think if you prep again up to 1200 or 1500 and a block then shoot. You will be better off. 1200 is WAY too fine for a final sanding before the base goes on. 600 is ideal, 1000 max. Above that and the base coat has little to grip to. At 1200 you're risking the base peeling loose of the primer at some point in the future. |

Whats the proper grit before- Primer on metal? Primer on FG? Base coat you said 600 Clear coat -shoot directly over base within manuf. time limit, or sand with ?grit? Thanks! |

Maybe a little smooth but I dusted the first light coat and let it dry for grip...looked rough at that point. then did the second coat and it went on smooth again. Still amazed how it came out for my first and only time painting anything bigger than a model. 3 coats and lots of sanding and polishing. 5 years and no peeling...a few chips here and there from my stupidity. I am not professional and am happy with the results. Total spend was like $110 for paint and gun; compressor I had. |

Actually my first attempt was a roller job...DON'T DO THIS unless you like sanding and prepping everything twice. (IMG:style_emoticons/default/blink.gif)

QUOTE(r_towle @ Apr 29 2013, 12:08 PM) did you say that the paint shop did it with the same results and now they are talking about what you prepped with? I think its the paint that needs to be questioned, not the people and process. rich As it turns out, the paint was bad after all. (IMG:style_emoticons/default/barf.gif) The body shop used it on a scrap hood and it turned out really crappy. The painter said he could tell from the way it came out of the gun, that something was bad wrong. They bought more of the same paint, shot it with the same gun and it went on perfectly. The guys from the paint store looked at it, decided it was bad (they said it didn't even smell right)? (IMG:style_emoticons/default/confused24.gif) and gave me more paint. Hopefully they will shoot it again this week. Kind of a bummer that my first attempt at this was hampered by some shitty paint. |

Really, the Dude mixing your paint didn't catch that. Mix some brake fluid in with his car polish. (IMG:style_emoticons/default/happy11.gif)
