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. |

So I got the suggested filter:
https://www.harborfreight.com/inline-desicc...lter-68215.html However, it doesn't seem to allow enough pressure thru. I have the hose going into the filter, then the pressure regulator, then the gun. With the pumpkin filter and the gauge set at 30psi, I get plenty of air. But, with the filter above and the gauge set at 30psi, I get far less air, the spray pattern is smaller. I tried it with two different air pressure gauges. Not sure what's causing this. None of my usual sources addresses this. I painted the hoods and am still getting a bit of orange peel. The gun also sprays intermittently, but only when painting; it works fine when I spray acetone thru it. |

The desiccant filter certainly takes a bit more air pressure to push through but it shouldnt be that bad. |
