I don't usually get negative here, but---get over it! I spent probably a dozen hours developing a double tipped iron, exactly one inch apart, that left perfect lines to pull up the strips. Then I wasted dozens of hours pulling up those nice strips. Months later I wasted more hours pulling off the plastic that was left, just to get back to what I should have done in the first place. Unless you have plans of building a polished plane, forget the whole thing, it isn't worth the effort. On the next three planes, I just stripped the plastic and was done with it, and there is no difference, when the paint is on. The plastic really won't protect from anything that wouldn't be polished out in paint prep. Just my two cents...
