Hey, I finally fixed the soft spots on the sides of the hulls on my h16. I used the west system and learned a lot. One thing I found out was NOT to use the slow hardner, I lost a lot of epoxy which ran down the hulls, I did not turn the hulls on their side. I had the hulls covered with masking tape which kept it from making a real mess, but sometimes the epoxy went through the tape covering the drill hole. I also had to drill a couple of screws to pull the glass back together, one word of advice if you do this is to go real slow If I used the screws again I would probably screw them in by hand! The hulls are now solid and I attempted to touch them up with gel coat. I ran out of the plastic to go over the gelcoat and used some plastic wrap, Big Mistake, they did not cure, so I had to scrape about 50 small pieces of bad gelcoat off and redo it, this time I used waxed paper, it worked well. I also discovered that if you use a very small artist brush , size 0, 00, or 1, to put on the gelcoat it works great! A dot will do a lot! One question I do have is if will the epoxy keep out the water if I don't have gelcoat on a couple of spots? Now I am going to wax her up and put her away till spring. See you, John
