Quikest way to age and stain Suede. Rub with a cloth soacked in vegtable oil, be warned though, irreversable. But as already mentioned. If something got torn or worn out, you went to stores and got it replaced , rather than be bawled out by the CSM as scruffy looking sod. As the old Stores man saying goes. 'If it fits, bring it back and we'll change it'.
