My final choice is:
Gtechniq's C5 wheel armour
Read about it here:
http://gtechniq.com/shop/3s-for-cars/ex ... el-armour/
Its by far the most expensive product but hopefully worthwhile! , this 15ml pot is around £25!
Apparently it forms a chemical bond with the surface and a single application lasts up to one year!

They advise protective gloves :shock:
Ok wheels came off today and I went through applying the gtechniq.
First off a top tip for anyone who likes to take pride in their wheels. Buy this:
Costs less than a tenner and saves the wheel from any scratches when removing/fitting.
First off I cleaned the wheels and polished the outer lips with autosol - Ready for the sealant!:
Then came the application, it is supplied with cotton pads so all you do is dip on the gtechniq and wipe around the surface. Make sure to wipe off any residue and get into all the cracks brake dust likes to settle.
Keep out of sunlight and avoid touching the surface whilst drying as it tends to haze up if aggitated.
application per wheel probably took 15-20 mins and was very easy.
Will update with longevity
