This is the age old Q the monza 2 is an awesome looking wheel imo,but as you have rightfully said its prone to the notorious white worm,i have had two sets of said wheel now, my first set had white worm and i decided to go down the very exspensive route of having them mirror polished with no laquer on them,which ment no more hassel with white worm but as they got duller then all i needed to do was get out the autosol.but when i got the wheels back from the polishers omg were they mirror lol wae to much bling for me so i sold them. i now am on my second set of monza 2 and altho i dont have white worm as yet i am considering having them re done as vw intended my local works is diamond wheels in dundee and have quoted me £65 per wheel which i thot was very reasonable and i am sure if i could get enough rims they would do us a deal on the forum.might be worth putting out the feelers.
