Does this really make that much difference?
Ive found a clean windscreen and a spray of fast glass everytime I clean the car seems to bead rain off nicely anyway....and requires much less effort!
I assume this lasts much longer though?? And what about dirt getting stuck to it, does it just get washed straight off with the next rain?
