I have found the same. My FJ gets pits in it. Super easy with aftermarket glass. I've been through four windshields and the last one I requested OEM glass. It is still perfectly smooth one year later. I live in Oregon so having the windshield wipers last as long as possible is 100% necessity. Once the windshield becomes pitted it goes through wipers like crazy!Two options on the protection... I have the new super clear XPEL windshield film and its been holding up great. The second option is protection plan and they apply a coating the plan is I think $700-$800 and it covers 5 years and multiple true OEM replacements if it cracks. Both options they have in stock at Gulf Coast Auto Shield here in houston. Ask for John Gray he is the owner and also has a GX550 OT+. He will make sure you're well taken care of. Google Search -- ALSO, coming from a 4runner with multiple windshield replacements from s reputable non-oem glass I am going to only put on OEM glass in the future due to the quality of non-OEM is typically bad when looking at it in direct sunlight you can see tons of specs and imperfections.
