Having changed my steering wheel on my startline for a nice leather version, I began looking for a new gearknob to replace the plastic one. New ones are £120 ish from VW so I was watching one on ebay that was obviously worn and when the seller offered it for £12 with the gaiter & fixing bolt I thought why not! I'd try one of those leather refurbishment kits to hopefully get it looking better.
Anyway, I got a kit from nuerapro on Ebay. They sell a 50ml steering wheel kit with cleaner, dye and top coat for 10.99 but found if you remove the conditioning cream from the 100ml kit this is only 14.99 so went with that. They sell a range of colours.
Just thought I'd post in case anyone needs to tidy up their leather - I have about 98ml (black) left if anyone local needs to borrow the kit!
