Just about all the boots we have used have had some sort of release agent
but I have never had any that caused de-wetting. Especially with 1A33. That
material wets better then most other coatings. i have had some that left a
residue on the tab that glowed under the UV light. The customer swore it
was coating.

We started using tab boots from Caplugs.com . Minimal residue. no dewetting
that we have seen from all the coatings we have used.
