I am making a set of guest bedroom furniture out of alder with a little birch ply and some maple. On the nightstands I primed them with thinned clear shellac (couldn't find any Sealcoat), which warmed up the wood and sealed the grain, and then finished with four coats of GF HP Topcoat. The first coat of topcoat had a bit of honey amber Transtint in it. They turned out pretty good, but I'd like to deepen the amber color a bit on the next piece. For the dresser, I thought about using regular amber shellac for the first coat, then sealing it with clear shellac, then going with the GF Topcoat. Will the clear shellac seal up the amber enough to keep from having problems with the topcoat?
