After the old varnish was removed, I used a cabinet scraper to finish the surface, avoiding the use of sandpaper.
Discoloured and scratched in places, but much of the original veneer still there. Character.
After an acetone wash, I brushed on two coats of
SP Eposeal 300 penetrating epoxy resin --
really soaked into the dry ply. I also brushed the stuff onto the underside of the deck, wherever I could reach
through a hatch cover or hole.
Then I draped 81gsm e-glass cloth over the fore and afterdecks using West Epoxy 105/207
consolidated with peelply.
