Epoxy will show your faults

Thought I was making progress with the fairing and sanding of the outside of the hull with Thomas. Decided to clean off the dust and give it a coat of epoxy for finish sanding before painting the outside of the boat. Rolled on the clear epoxy and every fault, dip, hump, scratch, dog hair and uneven surface came to light making the boat look like it had never been sanded.

Our sanding was just at the point of going too far - breaking through the previous epoxy layer into the bare plywood in a couple spots. I guess this means another fairing compound pass now that I can see all the trouble spots that had been hidden by dust.
