AquaScape Fix VS Polymorph Plastic

[Wilsoni]

I would love to purchase AquaScape Fix but can't seem to track down a reliable source.

With that being said, I'm wondering if there is any significant difference or benefit in using AquaScape Fix over the various non-toxic Polymorh plastic products offered on Amazon?

Amazon is a good source, my only issue is about the inability of macro encrusting of it. I've read it won't??
