Greg, It's quite possible that a thick old varnish finish would require a second coat of Dyna2 to strip to the bare wood. It takes 3 coats to remove my PianoLac, but that was 10 coats and PianoLac is much more chemical resistant than varnish, lacquer, or shellac. Except for polyurethane varnish. That's a tough one for any stripper, but Dyna2 will do it with 2 or 3 applications. If, on balance, you think it's better to use a methylene chloride stripper, even with health considerations, I'd be happy to refund the money you spent on the Dyna2. Bear two things in mind: Dyna2 has no wax. Gel methylene choride strippers all have wax, which must be removed with a toxic thinner and elbow grease, or you run the risk of fisheyes. Dyna2 dissolves and removes silicones, the nasty fisheye-making chemical that is in Pledge furniture polish. Arthur Grudko StarHawk Labs
