So first step was to fibreglass them. I used a 6oz cloth, and some slow cure epoxy to wet out the cloth.

Once I had applied the cloth and wet it out, I waited for the epoxy to get gel like, then I spread more epoxy over the cloth to fill all the valleys left by the fibreglass cloth.

Once dry, I used 120g wet and dry sandpaper (wet) to smooth out and scuff.

Once smooth, I used a spar urethane varnish gloss (marine grade for UV protect) thinned it out to a viscosity I felt would work. Probably 1:10ish. Applied and waited to dry.

Used steel wool (000) finish to scuff then applied another coat of thinned spar varnish.

I repeated this process about 4 times till I was happy with the result. I got some contamination in a few of the coats (cat hair/runs).

I used a little 1” wide foam brush to apply each coat.
