for ease of use and maximum protection id suggest either:
jetseal 109 x2 layers followed by collinite 845 x2 layers,
or
fk1000p x2 layers followed by collinite 845 x2 layers
or
i would recomend the Aquartz paint protection kit but its for pro use only due to its specific application prep/procedure etc so thats a no go im afraid.
what ive listed above will give your rims good protection as long as you keep them clean and top up the wax over a period of months, the jetseal or fk1000p will protect them from uv rays,contaminents,etc etc
and collinite 845 is a great long lasting wax and due to its fluidy nature in application its very economical if you just used it on your wheels.
i used collinite 845 on my gti rims and they stayed cleaner for longer and were a doddle to clean literaly need a light wipe with wash solution and no need for heavy degreasers,tfrs,wheel acids etc
also plenty of protection will prevent them from corroding.
hope this helps.
