I'm spraying with omni paint and as soon as its sprayed, it begins to peels and crack here are some photos it's only in a couple specific spots need ideas please. |
What did you do to prep the surface?
What kind of primer did you use? Those wrinkles are usually the result of spraying over something that is being dissolved by the solvent in the paint. 1968 Coronet R/T

yep you've got a compatibility problem, somewhere on there is something that's reacting to the Omni. as posted above you need to list everything that was put on prior to the Omni. also was the Omni a base coat and what was the oem finish or has it been repainted sometime back, all important things to know.

That looks suspiciously like lacquer underneath the Omni.
Either an area of factory lacquer, or where lacquer primer has been spotted in... "If you can't move it, paint it." - U.S. Army

I had bad wrinkling when I started spraying Omni basecoats but it was my fault for dumping too much on at a time and not enough of a flash time.
Sent by the random thoughts from the voices in my head...

Sprayed Omni once, that was enough.

I don't know why so many people get this backwards. Spraying a 2K product over an acrylic base (whether finish coats or primer) will NOT cause frying up. Spraying anything that has a highish thinner/reducer content over a feathered 2K edge or some thermoplastic finishes CAN cause frying up. Economy base coats and even 2K finishes have much higher thinner content and (therefore) lower solids than the premium ranges. It is this thinner content that reacts with the exposed and feathered edges. Fry-ups can also occur when base coat is applied over any 2K finish that isn't fully cured and also when used over iso-free hardened finishes. The solutions are: 1. Use a sealer or isolator. Epoxy primer works well. 2. If not sealed/isolated then apply initial coat(s) lightly and allow full flash off times.
This is good advice. Chris
