– Rain-X Rain Repellent & Anti-Fog Treatment Value Pack - Hydrophobic Formula for Clear Visibility and Fog-Free Windscreen - Ideal for Car Windows & Interior Mirrors - 200ml x 2

Repells water better than wax. Rain X Rain Repellent works perfectly on glass and plastics and lasts for a good while, no complaints. Rain X Anti-Fog is applied in a similar manor to Rain X Rain Repellent although can is slightly more tricky to apply. It does reduce fogging but doesn't eliminate it entirely. Take your time and make sure to buff off thoroughly. You'll know you've applied it poorly when you see small patches of condensation.

I deep cleaned my windscreen ,inside and out . The winter weather has been terrible and with road treatments ,the screen was manky. So ive never used this stuff its been out for years . An antifog for inside and the repellent for outers all in 1 kit. Nice. Once windscreen clean and wipers , i applied rainx . It went on very easy . The antifog was a little more demanding . On easy but dries smeary, which will cause fogging . Extra work req to get spotless . Antifog seems to work well ,im prone to windows misting up and they havnt yet so good. The rainx however was way more visual . I used on all the windows. While driving the rain streams off the sides . On the windscreen water dosnt hang around and with the clean winscreen and wiper i can see out in hi def . So all in all a big yes from me .

Seems ok Not impressed with the anti fog which i used on my helmet visor

I was a bit sceptical about this but for the price thought it was worth a shot. My car windscreen fogs up with little encouragement, to the point where you have to have the heat on virtually full time. I applied this per the instructions and it’s worked wonders. Got in the car after football on Wednesday and every window was fogged except the windscreen where I’d put the solution. Easy to apply, cheap to buy and works very well. Would definitely recommend.

Not very good wasn't impressed tried it three different times

The twin pack is a godsend for me. It actually works which I was sceptical when purchasing but gave it a try after a friend recommended it. Rain x really does make a massive difference in the rain and drastically reduces glare. Anti fog is brilliant too as my car isnt the newest and frequently got in to steamed up windows. This product has eliminated this completely! One downside is that it does take a bit of elbow grease to remove the residue after applying it but thats a small price to pay for 2 months clear windowless. Brilliant product

I followed the instructions completely and after a lot of wiping in a circular motion and very tired arms the product was no longer visible on the glass. This product is not easy to use, you will require some elbow grease. Unfortunately, the moment it rained & the humidity rose the usual internal condensation had been replaced with white circular smears making it impossible to see whilst driving. I had to pull over and use a cloth to clear the windows. This clarity did not last for long and took me over an hour to clean this product completely off my windows. Beware, removal is difficult and you will require a window cleaning detergent. As for external water beading yes it’s effective in forming beads but these beads do not run from the windows, they stay in situ until travelling faster than 30mph. Very disappointing, and dangerous as visibility was lost the moment humidity rose. Great value for money but very poor performance.

Rain X is easy to apply and works amazing, the only issue is I had to apply it every week over winter, and it became a chore, I have decided to just stop using it as it causes smearing if its running low, and it becomes dangerous. If you're happy to keep applying it every week then it is good stuff, to the point that I wouldn't need to use my window wipers at all and even in heavy downpours I had no issues.
