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. |

Upon initial review, it would appear that part of your problem is that you have condensation building up in your air lines,
which is also a direct result of working in hotter temps, and that condensation is being blown through the airlines and mixed with your paint. Please see the attached link to the video for a water trap, where the water is able to collect, without your pressurized air blowing through it. I can't say that this would solve all your problems, but would certainly help - Again, I am a novice painter, with no real world experience outside of primer - https://www.youtube.com/watch?v=IdxdbgeUUKA Attached image(s) |

(IMG:style_emoticons/default/pray.gif) I think you are right! I didn't really think of this until you pointed it out. I have the 2 water filters at the top, but I think I need to lower them so they are at the bottom of the line. Whenever I open them, there is no water. That seems odd, but I figure it's really dry here so no biggie. Is there a way to determine if water is in the lines, like spraying just air out of the gun and looking/feeling for moisture? |
