Bottom Paint

Just to refine that a little: If you can believe the manufacturers' propaganda the older ablative paints are good for just one season unless you go over them with something like a scotch pad to remove oxidation before you drop them in, whereas the newer copolymer ablatives are true multiseason--just drop the boat in so long as there's still paint on the bottom. My experience tends to bear out the first part of that statement. Haven't had the copolymer ablative on before this season, however, so I can't address the second part. I've never used the older-type ablatives of which you speak, rather only the copolymer paints. On my current boat I started with two coats of red Interlux Micron CSC followed by two more coats of blue. As the blue ablates, the red begins to show up. When the red is apparent in over 50% of the surface area, I recoat with two coats of blue. This is generally a two-year cycle, and I suspect it could be stretched to three if an extra coat of blue were used. Max |

They felt timing was an issue when applying "hard" bottom paint only. If the higher end copolymer ablatives live up to their advance billing that should clearly be the case, since you're supposed to be able to haul for the winter and splash the boat in the spring without doing anything to the bottom. As pointed out in a previous response, this is true. I only paint every two years currently, based on my two-coat program over a base of a different color for ablation monitoring. Max |
