My boat desperately needs a bottom painting, so I'm planning to pull the boat out for a few days and paint it with some fast racing paint. However, I don't have time to do the full sandblasting / acid wash job on the cast iron swing keel, but I'd like to make it a bit more slippery through the water. Any ideas? Will the West System products stick to cast iron? I'll do a more thorough job when the boat comes out of the water for the winter.

I've used all kinds of stuff to fair my cast iron fin keel, and many things work all right. I like "Marine Tex" and Interlux "Underwater Epoxy" best. What I think is most important, however, is to let it cure for 10 days to 2 weeks before you launch. When I launched the boat a few days after applying the fairing compound, the fairing compound was sometimes soft or it lifted off the surface of the keel when I pulled the boat out at the end of the season.
I use VC17 and have to touch it up on the keel each year before launch. It stays on quite well while in water, but some comes off when pressure washed when boat comes out in fall. On the fiberglass it holds on very well.
What's the difference between VC-17 and VC-Offshore? Also, there's a VC-17 with Biolux. I'd assume that the Biolux one is what I'd want in fresh water?

I guess that rules me doing that before the Nationals.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">The product description on the can usually says it cures in a day, but I don't know if that applies equally to underwater applications. Also, some of us amateurs don't always get the mix just right, and it takes longer for the stuff to cure. I did a major keel fairing job the day before the nationals one time, and the boat was really fast, but all the fairing compound was soggy when I pulled the boat out 3 days later. Heck, if the boat needs it, do it.
