VC17 Alternative

Anyone have first hand experience using the West Marine FW-21 branded substitute to VC-17? Is it made by interlux or another vendor? Aside from the sale price difference of 20 dollars, is there any benefit? I hate to be save a dollar now, only to spend two later on. Thanks!

 
I can't tell you anything except that the West Marine product is mate by Pettit.
If I recall correctly, Petit had a product called SR-21? that was similar to VC-17. It's seems to be replaced for 2017 by their black widow performance bottom paint. I would imagine you don't have any experience with any of these products since these are freshwater paints.

 
I ventured over to the west marine site and there are dozen or so reviews. All positive and some more detailed than others. The FW-21 appears to have slightly more copper content VC-17, but application, drying times and resulting finish are described as similar. It does not contain any biocide. If it producers the same smooth finish and low build up I'm inclined to try. I clean the bottom weekly, so I should know really quickly if it's anti-fouling properties fall short.

I have been using the West product for 3 or 4 years. I see no difference between it and VC as far as application, performance, etc. We take care of the bottom of the boat (J/30) and clean multiple times during the season. I have every intention of doing it again this season.

The Black Widow paint looks interesting. The old Baltoplate formula included Molybdenum, B W has that plus some other slicking stuff and they pimp it as "hard", so I'm thinking vinyl? Anyway, love to hear some feedback if anyone out there is using it.

We loved the Petit SR-21 on our Martin 241. We applied it annually over VC Offshore that was burnished to a polish. Lasted all season with weekly wipe downs with a sponge. We did thin the paint with SailKote after mixing the copper by topping off the can and shaking. When applying it went on very smooth and thin and left a very nice teflon finish.
