Barrier coat

This spring I plan on putting a new barrier coat on my boat. I think of using VC Tar2 or InterProtect 2000E. Which product is better to use and would make a better protection ? What would last longer ?

barrier coat

I put 6 or 8 coats of interprotect 2000e on my hull in July of 2004 and then a couple of coats of bottom paint over that. I hauled in Oct 05 and no blisters were present. The 2000e does not wear out as it is not your finish coat. Some type of bottom paint is.

I barrier coated my boat last spring with 6 coats of MAS epoxy. Then I applied one coat of black hard epoxy paint, and a coat of blue ablative paint. When I see the black showing through, it's time to repaint. Very happy with the results when my boat was pulled in the fall.

These are both good products, read the info on the Interlux website - use VC Tar if you want to use VC 17 bottom paint. We did the Interprotect because we wanted to apply Micron Extra. It was all good stuff to work with, just very expensive as is fitting...

My yard uses only the best (and most expensive) boat products and employs only certified workers. So, I had confidence in having them do my blister repair in their indoor paint shop during the winter of 2004/2005.

After using Peel-A-way II to remove the old bottom paint layers and grinding out all the blisters, which were very small and not deep, the hull was filled and faired with VC Watertite. For the following few weeks the entire hull was draped with plastic and secured to the heated concrete slab.

When moisture levels were recorded by my surveyor to be in the single digits, the hull was finally sprayed with multible coats of Interprotect 3000 epoxy barrier coat, then shrinkwrapped and moved outside. Since the final application served as a primer, all that I had to do below the waterline before launching was to apply three coats of Micron Extra with Biolux and install zincs.

Upon haul-out last season, the bottom still looked as if it was just released from the mold. This was an expensive job, but my philosophy has always been, if it's not worth doing right, it's not worth doing at all.
