I like the product, but had issues in the beginning with it. I checked with the manufacturer and they suggested I was most likely using too much of it. After reducing the amount I sprayed, I started seeing great results!
I just posted in another thread that I haven't used any windshield coating but reading this thread made me think. I buff my windshield using a microfiber cloth that has residue from waxing the body on it. I've been doing this for years on different cars and it works great with no streaking problems. The wax is P21S which I really like.
Yes but I don't see a need to. For one, you won't have that much wind force blowing the water away, and 2, you'll need a second package of aquapel unless you're very fast and get to the back and do a full application before it dries up.
Absolutely, I aquapelled the entire roof. It helps a bit considering we don't have a rear wiper. You will need to move really fast and maybe have a helper following with paper towels to do it all with one applicator.
I've been amazed in the manner with which water clears itself on the rear window at any speed above 40-45 mph (without any glass treatments). Well, I do polish it with rags containing wax residue. But I'm not sure that's what's doing it, I think the aerodynamics of the car keep the rear class clear.
I ceramic coated my windshield. I was so impressed with the slickness, I decided to use what I had left on the windows. I'm hoping due to the super slickness the wipers will not chatter for the times I do use them.
