If have to say that I'm well impressed with Poorboys Wheel Sealer.
After being on the GP since last December, and being used through loads of snow and also a few hooning sessions with some VERY heavy braking, the T.D. Imola RS have come up beautifully with only a quick blast with the K4 and a quick once o'er with a weak solution of Chemical Guys Diablo wheel gel.....
...enjoy the journey.
