Use cloth not mat. Start in the middle overlapping the keel by about 4". Let it overlap the chine and up the side and transom by about 4" too. Sand the overlaps a little once cured and do the other side of the bottom. Then do the sides. 4 pieces of cloth plus a transom piece. Youll need the edges sanded to a rounded edge for the cloth to flow over the edges nicely. Rounded about like a pencil. Use a tape line along your edges, when the epoxy is half cured you can cut the cloth along the tape line with a razor blade for a nice clean, straight overlap.

Ditto to what Vupilot said

I used whatever tape was on hand, in this case aluminium duct tape

DO REMOVE TAPE WHILE EPOXY IS STILL 'GREEN' don't ask me how I know this :)

My skeg was already in place since it was one piece with the keel and my transom was fiberglassed before mounting in on the building jig and I did NOT fiberglass my sides

Lay the fiberglass cloth out on the boat a day or 2 before epoxying and hand smooth it out daily ` it will lay out much better

Be absolutely certain to FILL THE WEAVE with epoxy on on the first coat or the cloth can 'ghost' through, don't ask me how i know this too.

Be prepared, I had 12 ounce cups at the ready and pre protioned potions of the elixers ready to be mixed go at a moments notice

May the Force be with you!

PS:

Be prepared for a marathon. You will need several coats of epoxy to totally fill the weave and not have to sand until after all the coats of epoxy are on,without sanding into the glass cloth.

You DO NOT want to have to sand the epoxy between coats, so you must apply each consecutive coatwhile the previous coat is still 'green' - not sticky but will take a fingernail imprint for lack of a better explanation.

I preferred to use a 'squeegee' to work my epoxy down into the weave, but that's what make life interesting, we can do things differently and get similar results :)
