Corona dope/paint?

Is corona a type or make? What is it for? I used to use dope (a long time ago) on model airplanes.

Mike.
 
How do you know you need such a product if you can't find evidence that the product exists? Why do you need it? Who suggested/specified it? Where did the idea come from that you should use it? What is your application?

Because, I think I learned about it in trade school or around that time and it was called corona dope.
 
Gc electronics,and waldom had that product. It came a jar with brush or spray.
Jeff at Chester electronics in Wisconsin may still have some..he has a lot of older stuff. If it's not high voltage you can get liquid tape at home depot in electrical supplies
