Sounds too good to be true ...
Was talking to my paint contractor who did a small job for me today and he just bought one for painting doors and other small jobs.
This guy is a very busy pro, and he only had good things to say about the Sherwin Williams model.
He seemed to think it would work for shellac, but I notice on the flyer that any solvents that are marked flammable are a no no, and that would leave out alcohol.
Urethane seems to be quite doable.
Some interesting youtube videos, but anyone with any actual hands on?
