OK guys, here's the scenario: Spent a LOT of time this weekend milling, dimensioning and cutting down a bunch of Maple to be used for interior casings around stationary windows we need to replace. LOML likes the softer look of shellac on the Maple. Me too, quite frankly. BUT, windows being what they are, get cleaned periodically and it's usually with some mixture involving amonia. Amonia doesn't play nice with shellac. So, I was thinking about putting on a coat of shellace to seal the wood and give it the softer appearance and use water-based poly for the second coat. Any reason these two shouldn't play nice together?
