Hard, slick paint!


I've just gotten done with a complete bottom job on my 1994 J80 (hull #90). This included an extensive blister repair, barrier coat, and then Black Widow. First, I would say this paint has a tremendous amount of solids in it. When you open the can, expect to see a big black glob. You need to stir this with a heavy duty, metal stirring rod on a drill. I broke two plastic stirrers that did just fine mixing up pretty heavy Interlux Interprotect HS. I had a gallon of the BW, poured off a bit, and then mixed it for 20 minutes straight. When you think you've mixed it enough - you're about half way there. I put some on from the first mix, and it was not a smooth application.However, after mixing it for 20 minutes and then thinning it with Pettit 120 (10%), it went on smooth and even. I used the foam cabinet rollers to apply and 4 coats went on great. Took just over a gallon to do the bottom and rudder. After letting it completely dry for 48 hours, we started sanding. I'm sure I could have put in the water at that point and it would have been much better than the 25 year old bottom that was on before. But we started sanding with 400 grit dry, then moved to 600 wet, followed by 1000 wet. Critical spots (rudder, keel, and the first 3-4 feet) got extra hand treatment of 1200, 1500, 2000. I tried burnishing with rubbing compound as the video shows, but this just made a mess. I used 3M rubbing compound (no wax) but it ended up with a waxy finish, so that got sanded off. I haven't gotten back in the water yet but looking forward to some speed improvement, especially in light summer breeze.

Black Widow - Fab Alternative to VC-17


Over-coats over old paint - no stripping, just sand with 80, paint a few coats, burnish and you're ready to go. Half gallon (two quarts) gave us to coats on our 22 foot mini-tonner. This was so easy versus applying VC-17
