Hey guys...The Interior Guy here,
Noticed you had a link back to my site on repairing a leather wrapped steering. Thanks for noticing me.
I first wanted to say one thing about the covers...They do more damage then they do good, they can not only rub more dye off but also leave impressions in the wheel which can also damage the leather even more.
You best bet is to have the wheel resurfaced. Sounds like what has happened to your steering wheel is that the dye has been rubbed off and the raw leather has been exposed.
Go to your local dealer and see if they can recommend a professional like myself to resurfaced the wheel. I do a lot of work for dealers and a lot of steering wheels. In fact I repair more leather wrapped steering wheels then anything else.
The cause for the damage is a number of things. Lotions on your hands, sweat, solvents, or just nervous rubbing. The leather is dyed with a water based dye which over time can wear off. But is definitely repairable.
So check with your dealer first before going for the cover, it just makes it easier to repair in the end believe me!
If you guys need anything, just let me know in here and I'll be happy to help in anyway
