I am getting ready to do my first Koverall covering job. I decided to just do what the manufacturer recommended (Sig) and so I bought Nitrate Dope as well as StickIt. I haven't decided which method to use yet, leaning towards Nitrate dope for adhesion and first coats (traditional). While you are not using Koverall and I am not sure what the recommended method is for your material, I read a lot on this and only a couple times did I read where guys use exclusively butyrate dope. I am sure it will work just fine but I wanted to follow the recommended methods for my fist covering job. Good Luck.
The shipping was a tad slow from Sig (Iowa to Wisconsin) so I can't imagine how long you will be waiting for it to arrive.
