Maybe paintings not my thing

[BigCars4Ever]

Well after my mishapps with the Pacifica Bumper painting effort I still had the nerve to try and paint my door. Things were going much better. 42% humidity makes a huge difference. Then I put the clear coat on and a Ladybug (good luck my a$$) lands in the clear and proceded to swim around leaving a 4 inch long trail. I plucked it out with a tweaser and thought I'd just hit it with another wet coat. Argh...should have waited. Now it's run city. Looks like I'll be sanding the runs out and trying it again. I need to buy some more patience.

i feel your pain. painting sucks with out a booth

It takes awhile to learn how to put on clear. Its got to be wet enough not to have O-Peel and not to wet to cause runs. After awhile you can tell were that fine line is. Good luck and dont give up!!!

yeah waiting would have been good.

the first coat should have been somewhat dry. followed by a medium wet coat second, and finish it with a third medium to heavy wet coat.

clear is tricky. each one is a little different. a lot of spraying them is feel for you gun.

I think I know what happened. I used PPG paints this time and the thinner is really aggressive. I tend to put down heavy coats so anywhere where I have spot primed or sanded between layers the thinner crept in and lifted. Even the PPG clear has thinner so you have to wait a long time time to clear after the final base coat so it wont lift. I think I'm going back to the Dupont products. I had much better luck with those.

Man you don't have good luck!

Wow, a lady bug, that sucks. I always hated the re-sanding when I had to fix a blemish.

I was refinishing a guitar once and when I had finally applied the last coat of clear and hung it up to dry the hangar broke and it fell to the floor and broke. I invented a few new swearwords that day.

Just curious, but what grit did you use for a final sand on the primer before you painted and then between coats? How many coats?
I'm going to be doing my roof in a week or two and any advice (except for those telling me to bring it to a shop!) would help a great deal.

I knocked it down with 600 then 1500 then 3 color coats. The first primer coat needs to be light. Then a light second coat and third coat. By light I mean enough to see the paint going on but not enough so it looks wet. Then after you sand apply a 2 light color coats and a final coat. No sanding in between. Wait at least the recomended time between coats and then some! Then I shot three heavy clear coats. I expected some orange peel so I wanted some sanding room. High solids clear souded like a good idea but it was really hard to judge the run point. I used a normal clear on my last attemt. It was a lot easier on the verticle door pannel.
My lessons learned: Patience, Patience Patience. Lighter is better on primer and clear. Finaly. Tape off the car as if overspray can find a tiny open seam and attack with vengence cause it can and did. Make it airtight!

Runs in the clear coat just means that it has enough clear applied, besides, now it is a signature series.... Mick Sagger:D.

Thanks a lot. Runs shouldn't be too much of a problem with my roof.

1500 is way too fine. Do NOT do this. Modern urethanes get mechanical adhesion only, from one cured coat to another. Not like lacquers which chemically bond between coats.

400 wet for solid, 600 wet for metallics, is what a body shop will use, to prep the substrate you are spraying over. Do the same. Putting color over 1500 is going to give you adhesion problems down the road. You need some tooth for the paint to bond properly.
