I've been sailing lasers (not my own) for about 3 years now. I've recently come across a 1985 laser, that is in absolutly horrendous condition. However after a couple hours of light power washing, i was able to find that underneath a quarter inch thick mud shell was actually a nice looking baot. Of course it requires a lot more work though. I was wondering if their is something I could put on the bottom of the hull to reduce skin firction, as their is a rather large amount of scratches on it, and if it would be worth my time to do it.
