I bought Comex ablative bottom paint
in La Paz
and had one of the Abaroa boatyards
apply it for me (part of the haulout deal I made).
The previous haulout, the boatyard recommended and used another, “brand name” bottom paint
(still inexpensive) for me.
I don’t know if the Comex paint I got was the same as PPG ABC3. I do remember that both bottom paints had about 45% by weight cuprous oxide.
By my unscientific observations, the brand name bottom paint seemed to have worked better. Then again, the second time around I was a couple of years older and in your mid/late 60’s, those years are hard. I very well may have been diving
my own bottom less for the Comex span of use.
When I get back to La Paz
, I need to haulout and have my bottom re-painted. I have been sailing to the islands way less and what’s left of the Comex paint is barely working at all in the “highly enriched” La Paz harbor water
