Shield is very easy to apply and it worked well initially, but after just a couple of weeks it started to be less effective as a rain repellent and was no longer beading as much as rivals. It’s excellent value for money, though, so having to use it more frequently won’t necessarily break the bank.

On first impression, the V12 Advanced Clear View looks like excellent value for money, but its bold claim to outlast the market leaders wasn’t matched by our experience during the test period.
To apply it, you just spray it on, let it dry and then buff it to a shine. Initially its hydrophobic qualities were good, but V12 Advanced Clear View lasted the second shortest of the rain repellents tested here, and after two weeks our wipers were smearing on the screen, with a strange milky residue from the product.

JokJok Glass Rain Repellent

It’s difficult to know where to start with the JokJok, sold through Temu. It comes in a tiny bottle with a pump spray action that empties the product in just a few squirts, though that’s enough to do a full windscreen.
But we don’t know why you’d bother. Despite following the application instructions to the letter, it was very disappointing. On first application, the water did bead on the screen, but after just one day of showery weather it had clearly rinsed off and had all but stopped working.
Verdict
- Gtechniq G5 Water Repellent Coating
- Rain-X 2-in-1 Glass Cleaner + Rain Repellent
- Turtle Wax Clearvue
Turtle Wax and Rain-X have both won this test in the past, but for 2026 there’s a brand-new winner in the form of Gtechniq’s G5.
We’ve been impressed with Gtechniq’s detailing products before, and this is one of its best – it’s easy to apply and effective. We also like that it can be used on plastics.
Rain-X is the runner-up. It’s still a very good product and is superb value. Turtle Wax Clearvue is also excellent and arguably marginally better than the Rain-X, but doesn’t offer such good value for money.
