i'd advise you ring other mirror polishers first, after you've regained the ability to talk, you'll realise 160 is a bargain!! places like renowheel in bridgend will quote from 60 a wheel, i'd estimate more like 75 for le castellettes!!
how long would it take you to do? (how long would i be without the alloys) you think it would last the winter and be good after aswell? does it wear off?
i could do them in a couple of days, and so long as you look after them, they'll stay like freshly polished for a long time, possibly indefinitely!!
ive got a few marks on the alloys slight curbing etc, would you be able to sort that out aswell? or should i try and get that done 1st? its not that bad but would obviously look better in better condition
