Well i have the black bunny boots, or BATA boots whatever you want to call them, and i know that they can deteriorate or get some kind of mold on them. How can i prevent this?? is there such a thing such as rubber maintenance??

I used to coat my rubber waders with vaseline and they never cracked or got moldy. I'd warm them with a hairdryer and spread it on thin and hang them up. It might be worth a try on the Bunny Boots.
