I didn't check the type because there were both duplicolor and I haven't had issues before. This was their engine primer with ceramic which I haven't used before with Indigo Blue Metallic. I did several light coats about 20-30 minutes apart for the primer then I came back about 4 hours later and hit it with the blue. It looked great that night but the next day it was blue potato chips.
Currently I'm semi gloss black engine with ceramic, blue, cast aluminum with ceramic and finally blue. There is at least 3 coats of each.
I really haven't used much of the specialty type paints. It must be that they are special enough that they aren't compatible with other formulas. If I do use something more specialized, I try to use whatever products may be in the same line, just for this reason. This thread make me want to paint something now.... too bad it's so cold here. I really should paint some snow blower parts...
Looking forward to your pictures!
