Wood, I’ve been coating my jonboat transom (fir exterior plywood) with OTF. I have four coats on the surface and eight on the edges and it still acts like a desiccated sponge. How many coats should I expect to apply before the straight spar varnish?
Cheers
Usually 3-4 coats of OTR and then 3-4 coats of full strength Spar Varnish and you'll be good to go.
