Wheel Wells, Rims and TiresRims, wheel wells and tires make a bold statement for the appearance of the vehicle, do you know how to properly detail these key components? Would you like to learn?
On the CG grim reaper bottle it states "do not use on paint" so i wouldnt use it, if you gpot the P21s why dont stick with that.
I have the P21s gel and I only use it on chrome or delicate wheel surfaces, IMO its really not a great wheel cleaner, especially on the tough stuff and its very expensive also. I think Megs WB is very good.
