Gary, if the weather is nice and warm in Texas so you can cure the covering to get it nice and tight so it doesn't sag in the hot sun then using more Tex for trim works very well. Sometimes I clear coat and sometimes not, at this point in my life I don't care if the plane gets engine snot and oil stains on it as much as I used to. To help with clean up then a clear coat is a good thing. If you have some white Tex on hand try covering a test strip and see how bad it bleeds or discolors over the dark. It may not be as bad as you think. Paints like the high dollar Klass Kote goes on very well with a brush and doesn't stink enough to worry about.
