I've read all the old posts on Vertglass. So a couple of years later, what are the opinions on the quality of this product? is it the shizzle? do you still use it? what do you think?

Great stuff and an easy way to get a great durable shine. However, expect to wash and apply another two or three coats per year or it will erode away and go back to an unfortunate mix of shiny and chalky.
