2 stage paint Options

[914itis]

I sprayed a 2 stage paint for the first time. I primed with a 2 k primer cut with thinner, waited an hour spray the base coat, 3 coats then clear coat.

I am not sure If i miss some spots or if it is a reaction, for some reason, I can see the primer under the paint. It's hard to see but can be seen with enough lighting.

It can be see in a few areas.

What did I do wrong and how do I correct this ?

First off, when you go in with a code for these cars tell them it is for a VW, not a Porsche. I have had many times when they couldn't find it under Porsche, btu could for VW. I have also had certain colors that did not have a formula in Deltron, but did in Shopline ( ppg's mid range paint ) I'm not a fan of DuPont. It''s overpriced crap IMHO. The ONLY times I have had paint reactions was with DuPont. The solvents are very harsh and will cause issues. Id go with Shopline for cost and quality. If cost is not an object go with Deltron, Spies Hecker, Glasurit, Standox. FWIW Standox IS Spies hecker, all of the chemicals are the same, even the labels are virtually the same.

My recommendation at this point is to just use the Omni. It's already on the car. It just takes more coats to cover, which you already have 3 on. Put another 4-5 coats on then 4-5 of clear if you plan to wet sand it once done. 2-3 if not wet sanding.

Switching paint brands at this point COULD be asking for bigger issues, and to do it properly you would need to reseal the whole car again to get a barrier between the old and new, if you use the Omni, you don't need to reseal, just sand, clean and re-shoot

The local supplier here will sell Omni and Deltron to pretty much anybody that walks in the door, but they wont sell you shopline? Certification? Shop Owner? Cant remember why?
