What's it for Keith, don't think the paint on the spec c would need it again yet but maybe the wheels do with the pads? Always preferred iron x over other stuff but have a load of autosmart fallout remover at home which you are welcome to try. They are basically the same thing except the fallout remover doesn't "bleed" so not as cool. Only big difference with the new stuff is that it bleeds now. They are on about it for years, reason they didn't was the cost of the chemical to make it bleed when touching iron.
