Quoted from bigd1979:
Really thats funny i have both and not any huge difference between the 2 imo . Pretty sure both have the coating which is why its so clear.
I keep telling myself that, but I'm really OCD in some details, and the coatings are definitely different. Invisiglass may have a coating, but definitely not the same as PDI, and for me, it's the top dog.
I've left the invisiglass in my WOZ, as I can't justify paying more ( machine came with it), but there is definitely a difference.
( not looking to debate this beat to death topic, just want to know what the hell is in that spray bottle, it works better than anything I've used)
