monokote will work similar to other films but smokecrater has it backwards -ultracote takes more heat and creates less gasses during application than monokote. hence, it is much easier to apply. it is also thicker than monokote and does not always go over open areas especially small ones like open stabs with out some wrinkling / loosening. also agree mixing the two for trim not good idea generally. also found ultra cote fades differently than monokote.
