Post subject:  Hull Repair Product Questions
The hulls of my H16 need to be repaired, as a novice fiberglass worker, what product types should I use?
Specifically: What weight of glass? What type of resin? Poly or epoxy? Any specific products you like or dislike? What grit of sandpaper?
If I don't care about the look, do I need to gel coat?
Thank you for any help!
Danny

The choice of materials depends on what type of repair you're doing. What exactly is it that you need to fix?

The bottom of the hulls have cracks in them and are worn down very thin. I want to reinforce and strengthen them.

Check this article out:

"The Bottom Job - This Old Hobie" by Rick Buchanan on pages 12 & 13 of the Sept/Oct 2008 Hotline.

Bottom job-

8oz glass tape in varying widths. Polyester (or vinylester) resin. Possibly 3/4 oz mat (if you need to rapidly build up areas). Sand paper, 80 to 220 grit for prep. Higher if you want to gelcoat and finish. A fellow Hobie sailor turned me on to the roloc sanding disk. Use it in a right-angle drill and it works very well for rapid material removal/prep. Acetone, brushes, mixing cups & sticks, dust masks/respirator, lots of disposable gloves.

Check out the above Hotline article too. Lots of good info there.
