I have a sample and just from a quick test with the product, it's not for the hobbiest that wants something quick and easy like Opti-Seal or OCW. If you don't work it into the paint, it will streak and the only way to remove it is to polish it off (washing, claying, etc. won't remove it). It was said a while back that 2 oz. will be about $90. Not sure if this is holding true, but it will not be cheap, regardless. Once I play around with it more (hopefully soon), I'll provide more feedback.
