I refuse to pay for wet okole waterproof seat covers. So has anybody made their own waterproof seat covers out of neoprene or the similar? I have been searching for the past two days on the internet and everywhere and nobody makes a cover that either totally covers the front and back of the seat, is relatively affordable or makes a cover for my application all together. I called about the Grant seat covers but they don't cover the entire seat. I tried exactseatcovers.com and they don't make a cover for my year model and their customer service sucks. Anybody?
