1963 Alcort Sunfish CHIP 19 Apr 21 Thickened Epoxy Skim Coat

19 Apr 21:

In order to seal up a few tiny leaks on CHIP's hull, we are going to spread on a very thin coat of TotalBoat THIXO thickened epoxy, but first we need to remove hardware and sand the deck lightly.

The keel strip on the wooden Sunfish is aluminum quarter round, about 18 inches long.

There are a few tiny voids in the deck where the plywood has checked, not enough to let water i but enough to let air out. Our experiment is to spread a thin layer of thickened epoxy into those valleys, sand, then prime and paint again. We used 80 grit to scuff the previous paint.


Leftover sanding dust turned the THIXO blue, which worked in our favor to help us see where the valleys were.

While we had the THIXO out we put a second coat on seams in the mast step and daggerboard trunk.
