HELP:blotchyishing paint


PUSHER

Recommended Posts

Practicing on my lip right now and am currently trying to primer it. I'm using an epoxy primer with an hvlp gun. What is happening is that I'm getting a thin layer of paint, but im also getting scattered little droplets of paint. I've tried different ranges of psi from 10 to 50, if I screw in the needle I get smaller droplets, if I unscrew the needle I get larger droplets. Advise? Should the paint being sprayed be the thin layered stuff or should it be the thickness of the droplets? Thanks.

I used Omini products on my truck and it came out great. I used a 7mm tip for the primer and set a pretty wide spray pattern. You may want to play with your gun patterns on a piece of carboard or body paper to set the gun correctly prior to shooting parts. When I paint cars, I tape up a large piece (6 foot x 6 foot) of paper on the wall of the paint booth. After filling the gun, I always "reset" the spray pattern by testing it on the paper.

BTW, for the color coat I went down to a 4mm tip.

sounds to me like a dirty gun or youve got water in your line. Have you taken your gun completely apart and clean it throughly I did that last week and was amazed at the buildup. i usually just spray acetone through the gun and or soak it over night. No more of that for me they get disassembled every time.

Hey, looks pretty good. On the blotchy primer how did you sand it? And also with the orange peel it just means you need to lay more paint down. I was scared when i painted my car of runs.. so i have peel in a few places. Runs can be sanded out but peel is much harder to get rid of.

I wetsanded the primer with 400. Do I add more paint during the clear or the base or both? I didnt really understand that I was supposed to soak the stuff in paint until I was clear coating. Planning on the hood and flares today, gonna try using more base.

Hi, new to the forum. I'm not a professional but I did shoot both my Z's with Omni. My neighbor who owns a body shop helped/taught me with the second one after he saw what I did to the first. He said it(Omni) shoots thinner than most paints so you need more coats than the P sheet says.I tried to get too much coverage with too few coats with poor overlap and got peel and runs and a 120 grit finish. Go light trying not to cover in one pass with approx 10-15 min in between (depends on temp/humidity).The first 3 coats looked blotchy until it started to fill in.Psheet says 2-3 coats , we did at least 4 thin. Use at least 50% overlap and watch the gun to part distance and your travel speed. He made it look easy being a pro.But he had me shoot half the car and corrected my many mistakes as I went .This is just my experience which I will use on my repaint but I know there are guys on here who are professionals so feel free to correct .

Looks great, also like the way the car sits. Nice combination of wheels and flares/suspension set up. Good luck with the rest of the paint. Most important thing for me was the gun travel speed and % overlap. Thats what ruined my first job. Best thing is to get a piece of 22ga scrap and prep/paint to test technique and gun pattern.
