Hi Guys,

Here is a question for you. A friend of mine (Del Paone) just painted a body with Duplicolor gray primer and then applied Testors One Coat paint (Purplelicious) over the primer and it, in his words, "curdled". He is an experienced model painter so does know how to paint a model and get good results. Has this happened to any of you guys lately? I thought that the Testors lacquer was a pretty "cool" paint and would not be a problem over the "hotter" (I thought) Duplicolor. But hey, what do I know? I've only been painting model cars for about 60 years now. Laugh

I've been using Tamiya primer for the last several years and never had a problem no matter if I spray Testors, Tamiya, Dupli-Color, Black Gold, or MCW paints over it.

Did he prep sand after primering? And did he let the primer cure for a day or so, or paint directly after? These are all factors.

When using a hotter base, allways allow an extra day for the primer to completely gas out. Then prep sand with a fine (3,000) grit, before laying VERY thin coats of paint. Give the paint as much time as possible between these light coats, allowing about three days to cure before a wet sand and final wet coat. That should cure the issues.

My favorite color is clear. I am also ambidexterous, I can screw up equally well with either hand. I am 53 years old and been building for most of that time. :)
