I use the .wet the silkspan and blot it on a towel ,method and apply over a twice doped frame and use thinner through the fabric to adhere it to the model. I use laquer thinner to thin nitrate dope and to apply silkspan. Laquer thinner will curdle the color in dope but works fine with clear. I have used "deft" wood finish instead of dope on my electric airplanes which do not require fuel proofing. Silk span can be applied over foam using thinned elmers glue but this again is not fuel proof! Jim Finn
