The original alloy pedals do wear out , depends on your driving position . I'm 6'1" and like to sit close to the steering wheel so it means i press the pedals more sideways on than on the top so i wore out the sides of the clutch n brake pedals . So i just got some grade A aluminium sheet and made some new ones . You wouldn't tell the difference between them and the original renault ones except mine are better quality and more harder wearing .
As to using autosol on your pedals . Do ya really want shiny , " slippery " pedals ? Especially with the wet ,maybe even snowy weather approaching ?
Your asking for problems .
