Look pretty damn good. I was patting myself on the back. Well I get home today and wet sand them with 400 grit everything is fine. I wipe the residue off with a micro fiber cloth. Then just to be sure I got all the particles off I use some rubbing alcohol on another micro fiber cloth and take them back out to the garage to shoot another coat.
Worst of the krackle peel
The front here is turned out and is very smooth "what it all was supposed to look like"
So 2 things because I'm not sure which is the culprit. Don't use rubbing alcohol. The other is temperature. The house is 70 deg the garage low 30 to high 40's "where the paint is" I'm wondering if because the paint was cold and the molds warm from setting in the house all night affected how the paint cured???? I can get it cleaned up with some more sanding just thought I was going to the polish phase of the molds by tomorrow. 
My NASA TT Lisence came today so it wasn't all bad 
Stay tuned we should be laying fiber soon. |
This could be from a few things, but im going to say that the paint wasn't fully dry when you applied the second coat, which caused the first coat to lift.
When applying paint, you either apply coats within 15 min of each other or wait the full recommended time allowed to fully dry, which some spray paints require up to 48 hrs prior to second coat. The alcohol i don't believe would affect it & temperature would only cause it to run. The other problem could be that you didn't clean it properly prior to your first coat. That + cold could have caused it to crack as well.
Either way it sucks! U have to sand it down as much as possible and clean the heck out iof it. Bring a heater or blow dryer when you're spraying. Dry it quickly to touch and bring it inside to dry 100% for 24-48 hrs prior to wet sand and final coat.
