Mix or Match on the boat's bum?
In the minor refit of my new-to-me boat, I'm getting to the point where I need to think about finishing the bottom.
I have no brand or type loyalty, just want good stuff to keep the growth down and to avoid problems.
Max speed 9 knots, to be kept in the Columbia River for the first year or two, with occasional 'vacations and long weekends' out into salt water. The biggest problem we have on the river is slime, that's why I was looking at the 'SR' type paint.
After that we plan to cruise the PNW for one full 'warm season' and then head south to the Sea of Cortez and other such places where we can stay perpetually warm and have essentially 12-hours of daylight every day of the year.
The only time we plan for the boat to be out of the water in the next 10-years is for maintenance that can't practically be done in water and hopefully for no more than a couple days at a go.
For the barrier coat the nice gent helping me do the bottom work has suggested 'Sea Hawk Tough Stuff' followed with a hard antifouling paint. He's also letting me buy at his price at West Marine. So off to West Marine to get schooled.
This is probably the 4th time I've asked about bottom paint at various chandleries. I gotta say the of depth practical knowledge at the retail level seems really shallow, getting a straight answer is tough.
The guy at West Marine was nice enough to give me the Pettit rep's number. Cool! I called the rep from Pettit and he seems pretty knowledgeable, double cool!
I asked about the difference between Trinidad SR and Trinidad Pro, he said "one label is color, the other is black and white". It's just a marketing thing, nothing more, same paint inside.
The rep said given my plan, starting with the hard paint is a really good idea, but be ready to use an ablative when we head south, and then he spouted the company line that when mixing brands of coatings, "If there's a problem, the 'conversation' is going be more complicated. Pettit paints haven't been tested on Sea Hawk's primers/barrier coats."
I don't know how big a deal that really is, what do you think? Does mixing brands matter or not?
