First off, please do not use this on any antique furniture or woodwork, that is what a proper Shellac finish is for. Putting polyurethane on an antique is the fastest way to ruin its value!That being said, I used this as a top coat on the picture rail in the Dining Room of my Victorian house over Modern Masters Pharaohs Gold paint. It worked awesome, dries fast, and is crystal clear.I am also using this as a top coat for all Lincrusta and Anaglypta in the house that is faux finished. It is the best product I have found for this! It is superior to regular water base polyurethane for this use.I do not know how this product would hold up on floors however. I suspect that regular or fast drying oil based polyurethane would be a better product for that use.This product has its place, and yes it is expensive, but for the right use it is worth the money!
