I have put some Iron-X in my order as well so ill give them both (that and the Sonax stuff) a try and see if it starts to shift it.
When I have had a good look at the wheels the back 2 are not too bad the O/S front isnt great,but the N/S front is the worst,looking at it half the wheel is covered in the brown stuff the other half is fairly free of it,so when the dealer prepped it they must have sprayed something on the wheels and it has dwelled and done its stuff (ish)on the bottom half and mostly run off and done not a lot on the top half.
Ill order some sealant as well like maybe the Gtechniq, I think but I always used the Poorboys wheel sealant on my Monzas on my Mk6 and they were almost as good as new,certainly much better than these newer Austins are at the moment anyway!
Anyway, thanks for your help, ill see what they look like when I have had a go at them and see if they are good enough for a picture!
