My worry about seriously hard coatings, especially ones that will dry fast with a curing agent is making a unsmooth mess that cannot be sanded smooth or removed, ruining, or at least uglifying a lot of very hard work.
I'd like to build it up with layers, so any one layer not being ideal can just be sanded smooth. But I don't want to have to do 37 coats, sanding between each one to get a smooth glossy finish either!
Really, I'd be happy to drop this stuff off at a pro shop and throw money at it until it looks great. But not sure many pros will know what to do, they seem to all specialize in something, and this kind of custom experimenting isn't it.
But there is a paint
shop very close to my workspace and they seem like they might be able to help. I'll be taking them one of my shelves and a cabinet door tomorrow (want those painted white too), we'll see what they say.
