Very nice detailing George.
I usually leave the small windows out and then do them with Micro Kristle Klear when the paint and decals are done. The thin film looks a lot better than the thick clear plastic. It works wit windows up to 1/4" x 1/4". I've even gotton away with a bit larger.
I have one of those magnifying lights too, but about a year ago the pin that fits in the clamp base somehow road up in the hole and the weight of the lamp bent it so now It won't fit in the base. Can't straighten out the pin because its made of 2 pieces of stamped steel and was mangled pretty good. Must think of another way to make it work because I sure miss that light.
