Both George and GPD955 need to find out what was Last used on their bottoms or they risk their new paint not adhering. Then check mfr. websites for compatibility. Nothing worse then watching hundreds of $$'s wash off your boat!
As to Trinidad SR vs. Micron CSC....I've used both and gotten at least 2 years out of both on the Bay but now prefer the SR for the reasons fastbottoms suggests.
