I came across a can of mink oil I used for water proofing boots when I worked outside in snow and rainy weather and It's hardly been used . It states it protects and keeps leather and vinyl . I'm curious about anyone having used the product on vinyl seats and such . It says it may darken some leathers . I've just spent a lot of time and effort cleaning my white vinyl seats and door panels and would like to soften and preserve them . If anyone can tell me if they would use this or the best/better alternative ! Thanks
