On the roll of Monokote is a paper wrapper around the material that has the instructions on it - I had problems applying the covering with out getting huge wrinkles and decided one time to read and follow them - it actually worked. On open structures like a wing you want to tack the covering down around the periphery and use a heat gun to shrink it down, then seal it over the wood areas with an iron. For sheeted surfaces like the fuselage it helps to tack it around the periphery and then seal it down with the iron. I have noticed from the little bit I've used Ultracote that is does seem to shrink more than Monokote, and area's that I thought may wrinkle didn't - the wrinkles came right out.

Learning to apply Monokote just takes some time and practice. It won't take long before you have smooth and tight covering.
