FWIW, Didn't have any problem getting bottom paint to stick to my Interprotect. I scuffed the Interprotect w 80 grit to provide tooth as on the instructions. No problems after 8 years. No problem getting paint to stick to later interprotect paint when I changed the depth and speed sensor thruhulls and Interprotected the fairing job before bottom painting. I did wipe the Interprotect w a solvent after scuffing w 80 grit. I think they recommended 216.

The Interprotect literature indicates you should apply the first coat of bottom paint before the Interprotect fully cures so that it bonds with the Interprotect and acts as a primer. You touch the partially cured material with a knuckle. When it is cured enough that you leave a knuckle print but it does not stick to your skin, then you apply the first coat. If I recall, it took about 45 minutes to cure sufficiently. Basically, very little will stick to cured Interprotect except Interprotect. Since I use Petit ablative paint, I put on a primer coat of hard Trinidad Pro. After it was cured/dry, I painted with the final bottom paint. No problems in the last 6 or 7 years. I can’t really say why the 6” or so along the waterline sluffs off, but that is what happened on Imzadi before I put on the Interprotect. I’ve been told is is because of the wave action causing erosion of the paint, but I’ve also been told that the UV is a contributing factor.

I've overcoated Interprotect with Micron CSX this way and had good results. Graham Collins Secret Plans C&C 35-III #11 On 2015-10-12 10:57 AM, Chuck S via CnC-List wrote: Brent, That's weird. I'm taking a quess. Maybe there was some sanding dust on the hull after sanding? Did you wipe the bottom with rags dipped in a solvent, before painting? Is it peeled off or worn off. Got any pictures?

I pulled Wild Rover out of the lake last weekend and found not to my surprise that once again I have lost the majority of the VC17 I painted onto the hull within 6 inches of the waterline. I originally brought the hull back to bare gel coat with a random orbital sander and sealed with 6 coats of Interprotect 2000. This was sanded flat and roughed up prior to the VC application. The Vc goes on as per the instructions but every year I loose that 6" or so. More where the water is turbulent. It's frustrating watching others pull boats with intact bottom paint, even those who clean their hulls every couple of weeks. Any idea what I'm doing wrong? This is all the more important as the zebra mussel infestation in Lake Winnipeg requires a good paint job. There were about a thousand of them on the little keel in front of my rudder which like the top 6" had lost its VC17 from the lower horizontal surface. Brent Driedger 27-5 Lake Winnipeg.
