I can not tell you about the Coverite primer or blue paint, as I do not know what they are for sure. I am just guessing on them, but I would think it would work fine. Almost anything will go over Aerogloss, but not the other way around. I would wet sand with 400 grit wet or dry before painting to give it some tooth. You should have no trouble with Sig Supercoat, or Lustercote, over Aerogloss, or Sig Supercoat. Do go slow at first to see how it reacts though, as sometimes stuff happens. Oh! By the way, Magicians are way cool planes. I am finishing my 4th.

I now know that the clear on the pane is Aero Gloss.   I only want to put other dope over it,  either Lustre Kote or Sig for the yellow and Coverite for the blue.

Actually,  I just found this on Tower Hobbies Web Site.  It answers my questions about it.  I should be able to use it.  Coverite is a brand of film.
