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. |

What kind of gun with what size tip are you spraying with? This one, with a 1.4 tip: https://www.harborfreight.com/20-oz-profess...-gun-68843.html I thought I would try a cheap gun first, then buy a nicer one, but this one seems to work fine. Everything I read said it's really the technique, not just the gun, that makes for a good spray job. |

Everything I read said it's really the technique, not just the gun, that makes for a good spray job. Thats certainly a good enough gun. The purple $15 guns are junk, but that one is good enough. My $600 gun works only a hair better than my $80 gun. |

My $600 gun works only a hair better than my $80 gun. I actually used a purple gun to spray catalyzed paint (basically spray-on fiberglass) on my targa top. I sanded thru it and needed to fix it and this was the best way. I figured I'd ruin a cheap gun. It actually worked pretty good. I read in several places about how the cheap guns can spray as good as the expensive ones. |
