I had a local make a wooden sign for the garden last year and a local car painter put a couple of coats of clear coat over the top.
Unfortunately the clear coat has come away and someone has suggested coating it in marine varnish.
Given that we are land locked down here we don't have any local boat builders to go and 'borrow' some varnish off.
Does anyone on here have access to marine varnish or have any left over from a project maybe? We don't need much which is why we don't really want to go and buy some as most of it would go to waste.
