Here's a question that, no matter how much I've read and tried to research, I've never gotten a definitive answer to, and I think it's a simple yes/no answer:
Shellac: Great for priming/filling/initially smoothing a surface, quicker drying, and so on. But, it's inherently not a tough finish, easily damaged, etc etc..
So, how about, on bare wood:
-- Seal coat with shellac to seal; sand lightly to remove the raised fibers.
-- Second coat, sanded lightly, finest reasonable grit, whatever it may turn out to be, as more of the same as above, but giving a little depth to the finish (I think)
-- Three or four coats of Poly or even varnish, sanded between of course, each time, for good adhesion.
IS that any improvement over just running grit to, say, 220 and three/four coats of poly/varnish?
Or is it overkill?
Or, would it be a complete waste of time?
I've used shellac on a few lamp turnings and man, they came out wonderfully great! But, for anything that will get some moderate use and might have any chemicals (water, oils, etc.), it doesn't seem to be much good unless one just likes the ease of touching it up, which isn't that great with liquid rings, etc..
Like many a woodworker/closet-cabinet-maker, I do great until I get to the finishes. I hate doing the finishes because I'm never sure of what I'm doing , even though they at least come out "OK", sometimes a little better.
TIA & Regards,
