We ended up using 4 4l tins of seajet platinum (2 part) for 2 1/2 good coats. Price
about $250/ tin. This is what lagoon
uses ex factory. Supposedly similar to micron 66 medium ablative, although it seems quite hard. Had a major hassle with barnacles
and ended up sanding
a lot of the boat back to gel coat. 3 days on the random orbital sander...fun...
Because we went back to gel coat we also applied seajet primer. I'll report back on the outcome in 18 months hopefully...
We also applied prop speed to the props and had a few issues with the primer gelling so we will see how long that lasts. So far so good but only a month of sailing since we hauled out at Grenada marine
. Grenada marine
was ok, a pretty nice little yard but we didn't have any work done by the yard contractors (who quoted me USD$2000) just to sand the old antifoul.
Quite a few boat owners were having hassles getting their works finished by the yard as they seem to leave things to the last minute. Who woulda thunk it in the Caribbean
If I had realised the extent of the work required I'd likely have sailed to Trinidad and had it done there. Itchy skin from dry sanding
antifoul and applying new antifoul then cleaning
it off with thinners reminded me of my boatbuilding days, grinding fibreglass in engine
Well what doesn't kill us makes us stronger (or dead quicker..)
As far as the seahawk issues, a lot of cruisers had replacement paint
supplied and possible haul outs paid for by seahawk so I guess they had a bad batch.
