Shellac on Sherwood BAC stain
This is my first post. I am a DIY with a little experience in woodworking and a little experience in traditional oil stain and varnish, but no real success with polyurethane and such. I appreciate being here.
I just finished a big kitchen cabinet project of mahogany, and I do not want to screw it up. This is what I am testing on the back of a cabinet door:
I used SW Sherwood BAC wiping stain, then one coat of Zinsser amber shellac, then two coats of Rustoleom water-based polyurethane (all brushed on with a sponge brush). The test is very nice: no blotching, beautiful luster from the amber shellac, and nice patina.
Sherwin Williams' fact sheet says that one has to spray on the topcoat on this stain, though I brushed on shellac with no blotching. I love shellac, and one layer of amber shellac lends a subtle golden touch to the "Cherry" stain I used.
My main question is this: since my test came out fine, do I need to worry about future problems?
Are two or three coats of polyurethane fine on top of shellac?
Should/Can I use clear shellac instead of the poly? I read that shellac will not stand up to heat, and there will be cabinets to either side of the stove. I love working with shellac; it is so easy to apply and repair. But if I have to remove it, this may possibly require me to re-stain.
I would appreciate any suggestions, especially from those who have used Sherwood BAC wiping stain before.
