RE: Koveral Appication
You will need a heat gun and iron, I went over all my seams with an iron and shrunk the fabric with heat before adding the coats of Nitrate. Dope will stick to epoxy. I always cover my tail surfaces before assembly, just cut a little material away where you are going to epoxy the tail surfaces on.
I have never tried Stix-It so i cannot give you any feedback on that product.
Good Luck!!
