Review on 🧴 P21S Gel Refill 1000ml by Roy Whetstone

I am restoring a '97 Land Rover and I believe the wheels have never been removed from the car and properly cleaned. I used this product many years ago and rated it highly, so I decided to give it another try and bought a new bottle of gel. I used a regular sprayer but it didn't work very well as another reviewer wrote. If there is a better gel sprayer I will use it. The back of the wheels was baked in 23 year old crap, I sprayed it as best I could (using a regular cheap sprayer, nothing to do with the product), applied it to the back of the wheel with a nylon brush and left it for about one hour. I flushed it out with a pressure washer and I'd say 90% of the crap came off. I repainted again and waited a bit and the second time even more crap came off. If your wheels have been as bad as mine this is the product, if your wheel just needs a good clean this is definitely the product. put them on.
