Looking for ideas to help extend the life and cleanliness of my black seats. I was nearly considering having some covers made to help protect from road dirt during traveling. I'm fortunate that 4 major lakes and the Delta are all within 40 minutes from my house so I do not travel that far, but dirt and grime; especially during winter wet roads can leave the seats looking a little discolored. Or is there a good spray on protectant I should be using to extend the life of the seat material?
