I recomend Supagard, i am a complete perfectionist & you name it i have tried it & always go back to supagard.
I have tried it on cars that have been treated & not treated & its works a treat.
My mums the complete oposite & never cleans hers unless i clean it for her & i always works a treat.
The cleaner works like a foam & easlily washes off & then apply the alloy wheel protector & that prevents the brake dust sticking so much .
The cans last for ages dependant on how often you clean them
You best bet is to get them of ebay
Hope thats helps |
