RE: Silk Covering Techniques
I too liked the clear finish on silk, and using acrylics my clear was near whitish clear. The UV additive I used didnt affect the colouring to any degree.
I got to talking to an elderly modeller over the weekend. We discussed the issues of silk covering a lot and the UV degradation was one subject we discussed. He said that while they were aware of UV degradation, etc he said they dint particularly worry about it so much, though with clear dope finishes the covering could get brittle. The painted covering faired better. But then as today, the life epectancy of a model wasnt all that long with few surviving more than a couple years without major repairs along the way. He also told me that models back then were usually stored out of direct sunlight, usually up under a roof of shed/garage or in a cellar. All in all it was a good couple hours we enjoyed chatting and it looks I might have help when I build and cover my next glider
