Completed my plane today and ran the engine. The oil residue wiped off fine , so far so good with the lustercote. It went on OK but not as even as an airbrush. Was maybe a little cloudy but that is hard to tell with the plane finished. Used two coats and it looks good. Flat Clear so no shine which is what I wanted with the solatex. Cannot praise the solartex enough. Went on like a dream.
