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. |

Here's the latest:
Still a bit of orange peel. However I think I figured it out this time. I would test the gun with a quick burst and the gauge would read 30psi. However, when I pressed and held it the pressure would drop. I re-adjusted the air flow knob. The air flow got quieter and sounded different. I discovered this while cleaning the gun. I really thought I had this dialed in before but apparently not! (IMG:style_emoticons/default/headbang.gif) What's interesting is the parts I sprayed quickly were turning out pretty good, like this headlight cover. It has a nice, smooth coat. That was because the pressure was higher: The good news is the body is ready to be re-sprayed, so I can apply what I've learned. The bad news is I need to sand and re-spray the hoods and doors. At least they will have lots of paint on them! It will also give me a chance to make sure I've got it this time. I only have a little less than a quart of paint left, too. |
