The tunnel cover on 420G is leather on top, vinyl sides, mine is ok, except the top leather has a somewhat mottled appearance as the grey dye has faded.
As everything else is ok and recovering one is a fairly big job, can anyone recommend a product and or method to restore an even grey color to the leather
Woolies in the UK do a easy to use water based dye. I was very impressed with the result. They do all the Jag common colours - or can match yours. The kit contained cleaner, dye and sealer. I found it remarkably easy to get a nice even colour. It was applied with a cloth and rubbed in.
I’ve had excellent results with stuff from lederzentrum.ch see Seat leather repair kit? for an example of their leather paint. They also sell a touch-up kit which is just a dye - find for correcting areas which are just buffed/faded.
Both work great on leather. Not so sure about vinyl.
