Quoted from DCFAN:...assuming this will be an equal or better product as compared to Invisiglass and/or PDI.
The competition Stern injects will hopefully be a legit equivalent product rather than a pretender like the guy that used to be on Pinside trying to sell glare reducing glass that was not even close to PDI and Invisiglass.
If Stern is branding it I'm sure it will be at least as good as JJP's product. I don't see Stern selling a lesser product. I always preferred PDI to Invisiglass but have them about 50/50 on my machines now.
Getting high performance glass is like an addicitive drug...once you have one sheet of the stuff it is hard to stop before your entire collection is done.
