Without seeing it, I'd still be thinking that what's on there is compromised. You can see how long it lasts but it might not be sealing properly and then, when some moisture seeps into your stone, it might hold more of that moisture in and for longer- the exact opposite of the purpose of sealing it.

Were I you I'd be tempted to soak a good lint-free cloth or non-shedding brush in denatured alcohol and neatly "slop" as much onto the shellac as I could, over the course of 10-15 mins or so- however long it takes to re-soften it. This will re-activate the shellac that's on there, allowing it to then cure moisture free, in a more even coating, and therefore make a newer and better and more durable seal. May as well slap a few 50/50 (equal parts can solution and denatured alcohol) while you're at it.

A quart of denatured alcohol should be a few bucks at any hardware store.

Anyway, good luck with it. It's always fun to experiment with something new!
Yup, I'm gonna start on that work tomorrow. Gonna try my best to get all the shellac off. Do you think running a little hot water on it would work for that?

I think if I can get the shellac off, I'm gonna stick to something like polycrylic (waterbased polyurethane, right?). I've used that before and it gave me no problems at all. Just have to get through the 19 inches of snow outside to get to the one Home Depot in Manhattan

Wish I could get my hands on some cashew lacquer. That would be pretty cool...
