We used MIL-P-23337 High Solids Poly Imide Epoxy Primer in the Missile
business. We used it not only as a paint but as a faying surface
sealer and as a locking compound. Great stuff. We would mix up a batch
into small specimen cups and freeze them. Pull them out when we need to
use them. It would be a good barrier coat material but I would expect
cost to be an issue.

I found a little bit of research from the US Navy about it.

The guy that did the job claims he's one of the only people who still
do this type of work in the Chesapeake Bay area. He raves about the
quality of the MIL-spec stuff. Said it is a 2 part epoxy (the same as
interprotect 2000 but way harder and better). 🤷♂️

All,
Has anyone applied a barrier coat lately and can provide some
advice on the number of coats to achieve the required thickness? I
will be applying with a roller and trying to estimate the number
of gallons to pick up at the Defender sale. Talisman will be
getting sandblasted next week and want to fair and then barrier
coat. Thanks!
