I had Micron CSC on my boat when I purchased it in Wisconsin. 2 coats lasted 3 seasons up there. I could have done a quick touch up, but wanted it to have a solid bottom coat in the waters down here.
When I brought it down to Florida last month, I re-coated with Micron 66. I'll let you know in a year or two what happens. I was told it worked great down here, so that's why I stuck with it. I guess time will tell.
