I thought I'd throw in my two-cents on this. This product may seem to good to be true, and it could be, that doesn't mean the technology isn't available.
You see, in my quest for the ultimate car wax/protectant, I came across a relatively new technology/application. Permanent and semi permanent coatings to protect the clear coat on modern vehicles. I am not speaking of your typical polymer based waxes.
One of the first was a product in Japan known as "G'zox real glass coating". If you've been to a new car dealership, you may have seen adverts for "Simonize glass coat".
Simonize should conjure negative thoughts to any car buff worth his weight, but that doesn't mean their new glass coat isn't legit. It uses a similar product/process to G'zox.
Heres a few links to these products
(in no way am I connected to any of them)
(this is in Japanese, but chrome will translate it)
(this site may not look as nice as some e-tailers, but his products are considered top-tier in the detailing communities.
I suppose what I am getting at, is that there are permanent liquid applied products, which are designed to add a hardened, clear, protective, and most importantly, permanent coat/layer
You'll find plenty of happy customer reviews for opticoat: google if youre interested.
I do however doubt Dynaflo is using a product in this category; probably just a clear polymer protectant.
