Perma Glaze

I was wondering if anyone has used Perma-Glaze before and how it compares to other products reglazing. I've never used, and now have a project that I need something better than normal, epoxy etc. I tried searching the comments but could not find any. Would you offer this product? What are its advantages and disadvantages or? Also, how would you compare this product with others like him?

Well, I think it's the best of the best
No other products compare to it at all
its just unbelievable
I use it a lot!
