Or you could just do what I'm doing and ignore it
. In all seriousness I should probably repair it, but in the nine years I've owned it I've shot a lot of trap with it and it still looks just like it did the day I bought it. I sorta follow the tenant of the mechanic who used to work on my MG; I'd point out some mystery noise or something to him and he'd say, "Well, it'll either get worse, or it won't."
