Griott's light protector



Griott's light protector film does say '3M' on the back, but the whole 
product is not manufactured by 3M. 3M do manufacture the stone guard film 
though.

The Griotts product is a 1mm (40 thou) thick PVC film with a 3M adhesive on 
the back. Whether Griotts purchase it as such, or put the two together 
themselves, you'll have to ask them.

The tricky part is sourcing the correct components. Film this thick needs 
to be optically correct, glass clear, uv resistant and reasonably flexible. 
The adhesive also has to be able to withstand the riggers of a range of 
temperatures and being pulled apart by the local car wash.

Just a little more complex than one would imagine...
