can repair but you need really good contact adhesive designed for the job. need to clean off all the old foamy cack too. not easy to repair the old material to look good tho as its likelty stretched and gone a bit funny in places plus can tear. go on edition loads of threads of people making their own custom linings, have a browse thru and see what stuffs they used
A local car trimmers did a repair for me.They did work for Noble too but are now just full time with Noble.Might be worth asking though.He charged me 30 to repair my sagging lining.
