I've just started revarnishing the 'dashboard' in our boat. It's teak veneer and due to poor previous applications over the years I've stripped it back and cleaned it down. I'm using Hempel Dura-satin which involves using 3 or 4 coats of gloss first, before a final top coat of satin. Although the instructions specify the number of coats and amount of thinning, nowhere do they comment on sanding between coats. Any thoughts? Interestingly, International Paints recommend sanding between alternate coats.
