There are two companies making dope products; one is Certified Coatings and the other is Consolidated Aircraft Coatings
Consolidated Aircraft Coatings | Home (Randolph, Polyfibre, Ceconite, Stargloss).
Brodak is Randolph and Sig "may" be Certified Coatings (Aircraft Spruce house brand) but I haven't done the litmus (smell) test.
Polyfibre is not dope but a vinyl finishing system.
Consolidated Aircraft Coatings | Our Products. The same for Stargloss.

Mixing the different products = disaster. None of these products work together. I use lacquer thinner from HD Aviation (or Lowes) to clean equipment and nothing else.
