For those of you who have used high-gloss tamiya clear-coats: how durable is it? Is it designed to provide protection, like Rustoleum lacquers, or is it more a sheen finish? Does it orange-peel (slightly bumpy finish)? I really like the Rustoleum I've been using, but it does have faint orange-peeling which requires polishing to remove. I don't get orange-peeling with tamiya paints, and suspect their clear-coats don't either.
