Never used the chrome stuff, but with normal U.C. or M.C. I wear a leather drivers glove on the left hand and use the heat gun for wing tips. I sometimes have to use sandbags (or a helper) to hold the wing or other object, to allow me to stretch the covering around compound curves.
Don't know the temp of the gun, but it's one of the old covering guns (T.F. maybe). Amazing how much compound curve the covering will stretch over, with the heat-as-you-pull technique.
As usual, YMMV!!
