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. |

Don’t overlook the quality of your compressed air if you’re having flaws in your finish. A filter/regulator mounted right at the compressor tank with a hose to your spray gun is likely not enough to eliminate moisture and oil that can spit out and cause fisheyes or what might be blamed on solvent pop. I don’t know what you have for a compressed air system but it’s important to trap the water and oil that can really screw up an otherwise nice paint job.

I don’t know what you have for a compressed air system but it’s important to trap the water and oil that can really screw up an otherwise nice paint job. I've got a 25' coiled hose from the tank to 2 moisture filters on the wall. It then goes out to a coiled 50' hose. I got a "pumpkin" filter at the gun. Interestingly, whenever I purge the moisture filters on the wall, no fluid comes out. When I purge the tank, I do get a bunch of orange water. Compressor is 8.6/6.4 cfm @40/90 psi. 2 (running, not peak!) HP, 33 gallon. |

I have used JUST this filter before without issue for minor work. I replace it after the media starts to change color. https://www.harborfreight.com/inline-desicc...lter-68215.html |

I was using the red "pumpkin" filters. |
