I purchased the Envirowax after watching a YouTube instructional on deglossing epoxy. It was recommended to be applied after sanding to seal the freshly roughed up finish. Having used the product for that purpose, it has worked very well.
Given the deglossed nature of my countertop, I do not know if I am receiving full utility from the Envirowax, I cannot tell a huge difference between pre-wax and post. (In fairness, I did sand up to 3000 grit.)
That said, the product does instill quite a bit of peace of mind. It feels more so protected than the unwaxed surface.
I am ultimately satisfied with my purchase. This bottle will last quite a while (a little goes a long way). It will continue to provide me with peace of mind for many years to come!
