[Paddlewise] Hull Repairs

I'm giving an evening seminar at my local kayak club next week on
fiberglass repairs, alterations, fix ups, etc. I was wondering if what I
plan on talking about and demonstrating aligns with what other kayakers
are doing for repairs. Some questions:

1. Deep hull scratches  -  I normally use a gel coat filler (this is the
paste variety, not the thin stuff), commercially available to match hull
color (usually white). You simply mix it with hardener, and apply
sparingly. You must mix only small amounts at a time. Does anyone use
any other product?

2. Excessive keel-line wear (usually near the stern)  -   I will either
use thick multiple layers of gel coat fill (thick stuff), or add cloth
impregnated with resin, then perhaps top off with gel coat fill. Does
anyone do it differently. I know one fellow who uses the thinner gel
coat resin, and works it right into the cloth, rather than using the
clear resin with the cloth. Any thoughts?

3. There was a discussion a while back, with reference to a product one
could apply to the wear points on the rear keel area. Anyone remember
the name of the product. It wasn't part of the normal fiberglass repair
product "family".

4. Anyone have ideas/suggestions/experience with glassing-in thigh
support within the inside diameter of the cockpit opening?

5. If you were attending a seminar, what would you like to see
covered/explained/demonstrated?

Thanks in advance.
