Weird reaction

T

tgwise

All SPI products used. Epoxy and Turbo primer. I sprayed the turbo over the epoxy. Had a couple of low spots. Applied Evercoat Zgrip. Sanded and finished with 320 grit. Re applied three light coats of Turbo. Now wet sanding with 600 grit. When I wet down it has this weird drying pattern that I haven't had before. It doesn't stay wet like the rest of the panel. I'm positive of the correct flash times. I'm hoping nothing is wrong here as I've gotta paint this weekend. I'm gonna lose the battle worth the weather as it's starting to cool off here.

The primer is still gassing off, kicking solvents out.

I don't think you have much to worry about, you'd be surprised how quick production shops jump on the turbo for prepping and painting and they don't have any issues.
 
Almost looks like some real thin spots in the primer letting the under layer affect the top but the pattern looks kinda strange, neat looking but strange. That would be my guess, looks like you need epoxy shot over it but wait to see what someone else thinks Barry, Jim and Crash are pretty good at looking at a photo for a fix.
 
Thanks, it seems to be just about normal now. It was drying really fast compared to the surrounding area. Wetted it down again before going to bed and was staying wet much longer now. I have plenty of turbo on it, I made sure the filler wasn't showing thru. I am going to shoot an epoxy sealer before paint. Hopefully it was just the gasses like suggested in the first post as I have not changed any procedures. I have been faithful with following the directions. Thanks guys
 
looks like a wall of schlongs. Its definitely something you could not do if you tried to do it..

Did you blow off the panel before painting it? Almost looks like some thinner was in the gun if you were using it to spray off the panel, or a mist of oil in stream of a blow gun. Its really the only motion I could see someone using before spraying.

It seems like Jorge M. was spot on. The solvents escaping at that time, would allow the water to evaporate quicker in that area than the surrounding area.
 
If Im reading the original post correctly, Zgrip was applied over turbo primer. I understood this was not best practice? Filler over epoxy but never filler over 2k primer?
 
Filler over urethane primer is not "best practice," but it gets done and can work with precautions like lots of heat and cure time. I think it is fine over aged 2K primers, but not really advisable on fresh applications.
 
Had friend that used some new at the time filler that was supposed to offer improved adhesion properties wrinkle his paint. Took him 3 repaints to figure it was the filler causing his problem.
