Barrier coat options

[wipe_out]

Hi,
We are nearly finished stripping the hull back for gel coat and while we have no osmosis I think it would be a good idea to apply a barrier coat since we are all the way back anyway and the keel has some exposed lead which needs sealing..

Seems there are many options, just some of the ones I have found are

West System epoxy with 422 additive
International VC Tar 2
International Interprotect
Hempel Light Primer (May not be suitable for lead)
Hempel High Protect II (May not be suitable for lead)

There seems to be overlap between products so does anyone have any recommendations for the above or anything else?

Also it seems the West System needs about 6 coats so if there is anything that needs fewer coats that would make life easier (and possibly less expensive) as well..

Thanks..

Ask AMC (Aquarius Marine Coatings, the producers of Coppercoat). They used to have** a family of high-build barrier products at sensible prices, with a long 'open' curing life, which is a major help in amateur application. Many people, me included, have found AMC helpful and responsive to queries.

** I'm assuming they still do, but have no recent information either way.

Jotun Penguard HB is what I used and would use again. Followed by Vinyguard 88 put on the same day as the first coat of antifouling, Jotun products are good value compared to International and they know marine coatings better than most. Like West they will recommend a total thickness so regarding the number of coats, surely having gone to this trouble you want to do as good a job as possible? The material costs of a proper job may seem high but it would be a shame not to take best advantage of all the work involved in preparation. In summer it is usually possible to apply 2 coats per day.
Boat was a Finngulf 33 with deep lead keel, most of the application was done with 4" rollers specific to the coating, ordinary rollers get the droop very quickly.
