I'm restoring a '15 touring and have just received the Cartouche upholstery kit. Not very happy with the accompanying instruction sheet or photos. Are there any links to videos, youtube, previous forums, that can help?
On Youtube, there are some videos produced by Lebaron Bonney that show a guy putting upholstery on seat springs. It's very informative.
However, with a Cartouche kit, your luck with it will be hit or miss. Some people have good results and others wished they had went somewhere else.
The instructions you got with the kit is all they provide.
