hey check this out, i've had these waterspots from having my car parked during a week of summer vacation under sprinklers a couple of years ago. minerals etched into the windows so bad that i have never been able to get them off even with my pc and any of my paint polishes. i didnt resort to steel wool though because i heard other ppl say it marrs the windows a bit.
anyway, this guy at my local tint shop told me about this stuff. it called "nothin's better." i'll let the pics do the talking.
cleaned with stoner's invisible glass:
product:
before and after:
if you cant tell the "after" is on the left side. you can see way clearer reflection. and no gross water etchings.
oh yeah i just got my windows tinted too, 20%. what do you guys think? i dont know how i like it... it actually turned out a little darker than i had wanted it to be.. too much contrast?
