: I am now starting the final sanding of the epoxy on the hull/deck of my
: guillemot. I have a couple of dumb questions for the all knowing kayak
: builders.

: 1. If i wet down the hull with water will that give me an indication of how
: the epoxy and/or varnish will hide the sanding scratches? I have areas
: that are matte after sanding with 100 grit, which dont wet out clear with
: water.

: 2. How does one tell when you have sanded into the glass (I warned you about
: dumb questions)? I have some areas that have had a lot of sanding (i think
: that I must be into the glass in some of these areas) which look just like
: the areas that have barely been touched with sandpaper.

: Thanks,

for 1: if you put another coat of epoxy on top of the sanded epoxy, all scratchs will vanish. Varnish will mostly vanish. However Vanish onto epoxy that has been sanded into the weave will stand out horribly in the sun.

for 2) you know you've sanded through and hit the fiberglass, because you'll see the white of the fiberglass. Usually this will look like a chris cross pattern. however if you have only one coat on, and are sanding for the first fill coat... you will have the chris cross pattern, the fiberglass is visible as being more white than the sanded epoxy.

That's my understanding, I still do not consider myself really experinced.
