Windshield coating is mottled

[Roarque]

2006 Gulfstream windshield glass has a distinct "mottled" appearance that reduces our vision in strong sunlight. I'm not talking about the Isenglass.

Is this caused by the "factory" coating?

Is there a solution?

picture?

you could be getting water/mineral spots. what do you wash with? do you dry/squeegee off? hard water in your area? any overspray from other cleaning/polishing/lubricating products you use (or that any close neighbor uses)? i get water spots if i don't squeegee off. ron

Is this only visible with sunglasses on?

Polarized sunglasses?

We wash the boat with fresh water after every trip in salt water and we both wear polarized sun glasses whenever we're on the ocean.

Are you suggesting that the polized lenses of our glasses is the issue?

I see it with polarized sunglasses on. The pattern is even so I figured it was just the way the glass is manufactured or something... So, what is it?

 

[ElyseM]

first, are we talking about you seeing this only with polarized sunglasses, or naked eye?

i will guess not polarized issue since you should be seeing that in almost all auto glass so should be used to it.

fresh water has minerals and chlorine in it. sometimes significant amounts of minerals (hard water).

I never see that in my car but do see it on Grady windshields mostly when viewed at an angle. I would guess it is the same effect as not being able to see what is on an electronic display when viewed at an angle. When cruising around the harbor I notice this on the boats with flat windshield glass. I have been told it has to do with the tempering process of the windsheild glass but don't know for sure. Put on non polarized glasses and it goes away.

 

[NOTHING ELSE MATTERS]

It is an effect that your polarize glasses produce. Looks like little squares or circles; it depends on the glass process.

What you're seeing is from polarized sunglasses & refraction.
The following product was recommended on this site a while ago for removing salt & other deposits from surfaces.
