Never used it, but I did some research, it appears the cross linking of the chemicals react in a way that increases the strength of the acrylic properties thus producing a finish that is nearly impervious to damages that other poly accredited finishes fall prey to. Also the biodegradable aspect looks to be more user friendly and environmentally friendly versus the other polys and such. I am going to purchase some to see how it would work, considering the covering is one thing but how it could help or discourage the sound aspect of a pot is another.
