i also put rain-x all over the car body. yep, not just on the windshield but all over. takes about 1/2 bottle to do it. result: di kinakapitan ng putik o dust car ko. if ever meron man, just a water hose gets rid of it without any need for a real wash. better than glaze.

check mo muna sa part na hindi kita to see if the paint does not react. most probably it won't do any harm naman.
