The products you referenced work really well. Water beads up and runs off the glass even when thewre is a dirt film on the window. Well worth the cost IMHO.
Cool, I'm glad to hear it because I have yet to use the sealer on a truck so I was wondering what your thoughts were.
We primarily use it on acid etched glass to seal out fingerprints and tongue lick marks.
Need to keep track of how long it lasts and if it eats up your wipers
Should last at least a year on the other windows.
