I have a 1996 Nautica 18' Deluxe rib that I've been restoring (former Navy rib). I have it re-powered and everything is working great. I love it! The only persistent issue is the tubes and rub rail are not in the best condition. The tubes leak some air after a day and don't look very good either. There are lots of small patches as well and they have been casted from the inside with some improvement.
I can't replace the tubes (out of my price range) so I've thought about applying tuff coat paint and/or wear patches to get it looking better and maybe help with the many pinhole leaks.
I also should probably replace the rub rail as it looks terrible and the top 1 centimeter is pulling away. (It works fine though and isn't coming off any further after a year or so).
Anyone have any suggestions?
