Primer and paint incompatibility?

I had problem with Testors primer and Tamiya spray (and will never use it again). As the primer lifts the paint getting cracked
I also found Duplicolor automotive paint getting cracked if applied over Tamiya primer. Never know what's going to happen when use it for the first time

Sounds like the primer layer is still releasing excess gas

Did you wait 24 hours?

Keep to the same brand of primmer and paint to save a lot of hassle.

I know it's the best way but there are some exotic paint suppliers like MCW Autofinishes and Cobra Colors. I'm gonna use 'em for factory matching colors and don't know how it react with my favorite tamiya primer

Anything good about Gunze Mr.Surfacer? It's kinda expensive here (~$8 for spray can). Worth to waste money? :rolleyes:

Certainly, experimenting Gunze is worth the money. And it won't be wasted unless you stop modeling. :) My experience with Gunze and Dupli color combination is that it works well. However, heavy wet coat of Dupli Color will definitely dissolve completely dry Gunze.

No matter what brand you use, the rule of thumb is...
* Primer has to be thoroughly dry
* First few coat should be almost mist-like light coat

As long as you stick to those, you can even use incompatible primer/body color combination when desired color is not available in appropriate paint type.

Cobra Colors has ceased operation as of the beginning
of February,
Leon said I was TOO profitable to keep as a part time thing but
not good enough to make it full time.
