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. |

I think I spray at 20-25psi. With the nozzle a stretched hands width (pinkie to thumb) from the surface. Fan the spray pattern for a consistent spray with 12-18" coverage. Moving at a slow walking pace, if I spray a whole side I walk leg over leg facing the panel and keep my body loose but my arm semi rigid trying to keep a horizontal line over the panel and the depth consistent.
You want to sand the body perfectly flat with 400. You dont want any valleys or else they will transfer to the final finish. The smoother it is prior to final paint the smoother your final spray is. |
