Question
Dope Over Dope - different brands

I have a few airplanes I doped with Deft brand lacquer and it didn't seal all the way like the Sig brand does. When it's humid the Deft sealed tissue sags. I'm wondering if I put a coat or two of Sig dope over the Deft coats will there be problems?

Why not put more coats of Deft on? It would be safest. AFAIK Deft "should " be coverable with either nitrate OR butyrate dope BUT NEVER Nitrate/Deft over butyrate. Good idea to test first, just make sure.

packard, I hadn't thought of that, maybe that's what I'll do.
