: Two things will produce waves in the glass.

: Too much resin will float the glass. This is why it's important to
: squeegee off the excess so the glass is right against the wood.

: Wrinkles in the glass. Sometimes the glass will hold wrinkles and because
: the resin does not have any tack strenght it will not hold the glass against
: the wood.

: If you try to lay glass onto tacky resin you'll have more problems than
: whackin a hornets
: nest. If you have wrinkles that pop up from glass that won't lay flat, you
: can try going back
: and rolling it down when the resin does develope tack with a special metal
: roller ment to
: remove bubbles or you can just sand it flat.

I had hours of trouble glassing the inside of my canoe, in part because the epoxy was still slightly tacky (it actually did not feel tacky to the touch, but the cloth still stuck to it). I have tons of wrinkles, cuts in the cloth, it would not lay flat on the keel (air bubbles).... Argh.

It may work better on the outside of the hull, but I would not try it.
