+4 on PS!! Great folks there and great products!!
I was lucky I still had my original windsheils to work with in having them etch the new one!
They explained that the originals were sometimes etched so they read left to right from the inside, and others were just backwards to this, I don't know if it was a plant/supplier specific thing or not but its all in the details to get it right!!
ALSO: PS did the replacement door glass for my '65 K code convertible in the Sun x tinted and besides the etching matching perfectly the glass itself matches the 45 year old original vents and quarters!!
