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. |

Lots of good tips about air and what not, but based on some info you gave us I think we're missing the bigger problem.
If you're standing through to primer with 800 after 3-5 coats and not through the orange peel, then your coats are way too dry. Make sure you're laying it on wet. Better to have runs (can be fixed later) than dry spot. I would stay no more than 6" from the panel and really get some paint on there. Slow it down and practice on a piece of masking paper or something first. Tetz has a really good example about taping a paint brush to the side of the gun 6" out so you can feel exactly how far that is. Hint: it's closer than you think. Also, try dropping your PSI at the gun some and see if it helps. I just sprayed my car and lowered the inlet pressure to around 25. I laid it on pretty wet and it sprayed like a dream. Lastly, make sure to use compatible temp hardener and reducer. You mentioned using medium with slow. Try and use slow for both so there is no possible mix-match. I know that you are been overloaded with info from all of us. My suggestion is to try one new thing at a time and see if it improves on a test panel. Too many changes at once and you'll have no idea what made it better or worse. |
