[C320-list] Minor issues with hull bottom

[John Meyers]

Troy, and anyone else,

This may not apply to you in your repairs.

I have made several gel coat repairs above the water line after watching
the videos, which I agree are very good. However, the videos show repairs
that are horizontal and my damage was on vertical surfaces and the liquid
gel coat sagged which caused a second and third application. THEN I figured
that if I let the gel coat firm up before I put in on the damage it
wouldn't sag (as much) and I would need to keep working the gel coat until
it hardened up. Now the problem is that if you are fixing more than one
spot you need to work fast once the gel coat starts to harden and you need
to go back and forth for spot to spot. Then, after letting it cure totally
then sanding with finer and finer grits. A second application of get coat
was needed on some spots. Once it is all done it really looks good and is
very satisfying.

Another note, I purchased the gel coat colored for my model year. I cannot
tell where the repairs were made.  I got it from www.*spectrumcolor*.com.

Good luck
