Solid Hardwood, Engineered and Laminate Flooring - Applying Poly to Laminate

I've got some laminate which is badly scuffed. If tried some of the urethane laminate "polishes" like the one from Bona a $20 per quart. I found tha the Bona was a soft finish and wore through in a few days, exposing the scuffs or damage to the laminate. Bad deal.

I've run into two products which claime to be able to acid etch or abrade the laminate (in a safe way)m then setting up the laminate to receive the poly.

The two makers (may be the same company in fact) are Varathane and Wood Solve.

These kits are not cheap and are a little scary. both sell for about $10 for a quart or so of the abrading fluid and a gallon of high solid poly.

One experienced floor man said he had a 90% success rate in getting Wood solve to "stick"

Curious if others have tried similar approaches, or if there is any really "hard" finish - unlike Bona, which will hold up.

The two makers of poly recoat over laminate, WoodSolv and Varathane both say it works great. Anybody actually tried it?
