Hello All,
I use the old fashioned finishing system of nylon or silk with dope for the wings and tissue on the fuselage. The nylon for practice machines and silk on the bigger stunt planes. OK, I now use mylar under the silk, so not quite as old fashioned. I dye the silk before use and I even use printer ink in the clear dope, for the decoration. For fuel proofing, I spray on, what I believe is, a polyeurethane floor varnish! All this is to get the weight down. The result is a very lightweight finish that lacks little in strength.
I don't aspire to the superlative finishes that weigh a lot, but any ideas to make a lightweight finish look a little better, would be appreciated.
Regards,
Andrew.
