problem with brake cylinder rubber boot

[edge19lw]

So, today i was changing the rear pads and i punctured a small hole in the rubber brake boot. I really dont want it to rust or anything so is it possible to purchase one at the dealer? or can i patch it up with some type of silicon. (I'd like to buy a new one but i'm not sure if the dealer has them cause they're closed now) Thanks everyone!

It's just a dust boot, a dab is high temp silcone will fix it.
