Baltoplate Performance
I've used Baltoplate in the mid Cheasapeake Bay for the last 15 seasons as a racing paint capable of being wet sanded to a mirrror smooth surface. It is now sold thru Interlux. When it's wet sanded and scrubbed clean, you can't get a faster bottom, but algae/ slime grownth starts up again and becomes a factor after about two weeks in our brackish water. We don't race as often anymore but I do scrub the bottom with a 3M grille scrubber about once a month to remove slime - never get any barnacles though except on the un protected folding prop. However, due to the work involved, I would NOT recommend it to any but serrious racers. Once you start using it you may have to sand it off completely to change to another material due to compatibility issues. The solvent in the vinyl based paint also starts to delaminate most any paint rollers I've used including the West System foam rollers used for epoxies, so I change rollers after about 20 minutes. VC 17 is the other racing performance paint we hear about most up here, but I have no personal experience with it.
