I just re covered a 40 Stik with Sig Koverall & dope. After sealing the Koverall with nitrate clear, I applied (sprayed) my color coats with butyrate dope. I did a step, by step thread with pictures of the process on another site. Heres a finished picture of the Stik recovered with Koverall & dope. All up weight ready to fly just over 6 lbs......Gene
