So I painted my car. Got some orange peel, thought I'd see if anyone had ideas for getting rid of/minimizing it.
After painting: After sanding with 1000 grit. The lighter areas are where I sanded, the darker areas are the lower points of the orange peel: Option 1: I'm thinking I need to go to 800 grit, then 1000, 1500, 2000, then polish. Before I do I thought I'd see if anyone else thinks this is a good idea based on what they may have done. Option 2: I can re-paint it. I'm thinking I will sand with 400 grit to rough up the surface and then re-spray. Option 3: I can polish it more, but the orange peel is still noticeable on the smaller pieces I've tried. I used a Torq X polisher, white pad, Chemical Guys V32 polish. I thought it might get smoother as I polished it with finer and finer pads/compounds, but I don't want to burn thru the paint. I put 3 coats of paint on. |

Thanks all. Here are my responses:
I'm letting it sit for a week before sanding. The paint supplier told me to wait that long. I didn't think it was solvent pop causing the pinholes, thanks for pointing that out. I wait 15 minutes between coats; maybe I should just spray one coat, or wait longer. I wipe the surface down with surface prep (Prepall) right before I spray. My paint area isn't perfectly clean, and I've got a few bugs that have landed in the wet paint. They just sand out. But, for the most part, there doesn't appear to be any evidence of contaminants. One thing I heard over and over was "CLEAN the surface, then clean it again!". I looked on youtube and elsewhere to learn. I thought I had this down. I painted a hood a few months ago and it looked great. I think I need more specific help pertaining to my situation (the weather, psi, equipment, paint type, etc.). I thought some of you might have some insight, so thanks! (IMG:style_emoticons/default/beerchug.gif) I think Oscar is right-the weather is not helping. I'm even using high temp reducer and hardener (for 85-100 degree conditions). It was about 85-90 degrees (50% humidity) in the garage when I painted at about 10 am. I can paint at night, but I think it pisses off my neighbor. I'll try one more coat (early in the morning) on a door at higher psi and see what that does. I'm going to dial this in on the doors and hoods before I do the car body! |
