Forget Rain-X, this is the stuff you want.
We all know about Rain-X, you put it on your windscreen and wipe it off with a cloth.
Then for the new few weeks you will find that rain clears itself from the windscreen
over a certain speed so you don't need to use your wipers.
The repelling qualities degrade fairly quickly and it needs to be reapplied to keep it working well.
Now imagine the same thing but one that lasts for months instead of weeks,
you have just imagined Aquapel.
There's nothing quite like a quick movie to show how easy it is.
The first thing to do is to clean your windscreen as thoroughly as you can before applying Aquapel.
Aquapel comes in a clever use-once applicator. It contains a glass vial that is broken by squeezing
the applicator wings together. This allows the fluid to flow onto the applicator pad.
Wipe the applicator pad over the windscreen, up and down then side to side.
As soon as you have finished applying it, start removing it, don't wait for Aquapel to dry.
The instructions tell you to use a clean paper towel, this is crap advice, use a clean microfibre cloth.
To continue to ridicule the instructions it also says don't use in temperatures BELOW 500F
and above 900F, that's 260 degrees celsius and 482 degrees celsius respectively.
I think we can safely assume they mean between 50F and 90F (10C and 32C), seems more likely.
Once it has been applied and removed, you can clean the glass with normal
glass cleaners without affecting the Aquapel coating as it bonds to the glass.
I applied Aquapel to my car in March and it's still working strong 6 months later.
The speed required for the water to run off is a little less than Rain-X too.
One thing worth noting is that there seems to be enough liquid in the applicator to do more than 1 windscreen. I managed to do every single window on 2 smart fortwos with 1 applicator so plan ahead and share with someone else if you don't have 2 cars.
Yes it's more expensive than Rain-X but then it's way better so think about giving it a go.
For £9 you can buy the kit from SmartMods and do 2 cars so why not team up with a friend?
Long Term Test
Aquapel worked wonders for about 9 months and then the effects started to fade slightly.
The rain still ran from the screen but you had to drive a little bit faster to make it happen.
Even a year later it still clears the water but it could do with a reapplication I think.
