As Doug says, it depends as far as masking goes. As a process, we will not
mask when using the ultra-thins unless a customer starts asking for
multiple coats exceeding 1ยต in final thickness.
I think one of the best uses of materials such as Novec is as a
supplementary coating to maximize coverage of some protection everywhere.
