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. |

Here's the latest. I sanded with 400, cleaned with a red Scotch pad and something called "prep and wash" from R-M. I mixed the paint with a little extra reducer (4:1:1.5). The engine lid turned out decent:
The doors still got some orange peel. Not quite as bad as before, but still not what I was hoping for: I turned down the amount of paint (1-2 turns) and sprayed at about 10-15psi at the gun. It was 81 degrees and about 40-50% relative humidity. The first coat went on well, then I waited 15 minutes for the paint the flash, then did a second coat. The second coat seemed to have more orange peel. When I paint, should I just paint a first coat then paint a second coat right away? In other words, go over the surface twice on the first coat?
