Was feeling a little adventurous this weekend and decided to really attack my wheels. Turned out to be very time consuming and was only able to finish the two front 19" rims of a 2010 Jaguar XF.
Before shots were taken following my standard wash using the GWC, Turbo Stick and the Boar's Hair Wheel Brush.
Following removal, soaked the barrels and rear of the spokes for about a minute with GWC then cleaned using the boar's hair brush, lug nut brush, toothbrush, random towel.
I park in a garage without a water supply so used a pressurized garden sprayer to rinse the wheels between phases.
After getting them as clean as they were going to get, clayed inner and outer surfaces, applied Revive Polish, and topped it off with MSS. As I sat waiting the obligatory 20 minutes for MSS to cure, I really wished I had a can of Adam's Speed Sealant.
The results. Not as perfect as I wanted but significantly better.
