Skip the deep bevel entirely. That hand routed look is a pain in the ass to keep clean, and the chipping issue is just the start. I've seen three different bar tops with that fancy edge in the last two years, and every single one has a cracked corner or a gouge where someone dropped a glass. The finish will flake no matter how much sanding you do, because the angle is too thin at the lip. A standard rounded over edge takes a hit and just bounces back, but that deep bevel catches everything. Plus, that light effect the owner bragged about? It shows every single smudge and water ring like a spotlight. You'll be refinishing it every six months just to keep it looking decent. Simple 45 degree chamfer with a hard wax finish is way more practical for actual use.

I actually keep mine in the house now, never had luck with the garage.

Wait, who's actually teaching these workshops? Is it some Gen Z kid who learned from YouTube or an actual old timer who used to work the switchboard?
