As in the arteries, the walls of veins have three layers, or coats: an inner layer, or tunica intima; a middle layer, or tunica media; and an outer layer, or tunica adventitia. Each coat has a number of sublayers.
The object is to build the layers of varnish as thickly as possible. Varnish will only last if there are at least 8 good thick coats. Allow 24 hours between coats, and sand using a block and 280 grit between each coat. Donât worry about getting a great finish at this stage. When you have 6 coats your varnish should be looking pretty good. When you get to your final coat, make sure your brush is very clean.
