Query: If something seems too good to be true, it probably is.

This is like an As-Seen-On-TV product: great concept, but really poor in execution. We loved the idea of a paint stripper that's not made of harmful chemicals, but if it doesn't actually strip paint, it's just environmentally-friendly hair gel. We tried it in a number of thicknesses and durations on two separate kinds of paint (both on concrete, neither of them stains), and to call the results poor is a compliment. It didn't even affect/soften/disturb some places after a thick application for many hours. I know it's tempting to try this product because the options of how to remove paint are few, but don't. It's rubbish.
