Jeff is definitely right about the cost of repainting soft over hard. It''s my understanding that you can put Micron CSC over almost any coating in good shape. VC and Baltoplate want everything else stripped off first.
It is my understanding that the harder paints can be sanded to a smoother, glossier, and hopefully faster finish. Also that finish will stay longer, as the paint is not dissolving away on you in random bits.
I think my plan for this year is to sand out the CSC on myu new boat as smoothly as I can, hire a diver for the summer, and they completely strip in the fall and apply BP.
I did a little poking aournd in catalogs too. Baltoplate used to come in a yellow can, and I believe was not an Intgerlux product. Now Interlux lists "Baltoplate Gray" as one of it''s VC offshore colors.
