first product i used was meg hot tire shine.. loved it the first time and havent bothered trying anything else.

i actually used it on my tires on June 4, and since then ive been away from the G37. I won't be driving it (neither will anyone else) until august 14.. so when i see it then ill let you know if its still shining like before

 

Wolfgang Black Diamond Tire Gel... Tires are so wet, the wheels look like there sitting on oil!
