anyway to fix it besides getting new tape?
glue a reasonable idea?

nope. new tape.

I just tape it over with eletrical tape.

Though these days I don't use any - it's cotton or grips.

New cork is nice, but old cork ain't so nice. Cloth is all-around better. Comfy enough, longer lasting. Old-school too.

C'mon, it's a coupla bucks. Old cloth gets pretty skanky anyway. Go for new. You'll look all new and purty.

absentr's got it going.

elec tape makes it last forever. plus, it gives you street cred.

I had this old yardsale bike with black cloth tape that was faded and frayed to such a perfect patina. I was loathe to replace it, and I rode it that way until the fraying got out of control and my comfort was actually suffering. Ah well so much for street cred. It looks too shiny and new with new black cork, but it sure is comfy to my hands.

I once saw someone who had their bars entirely covred in duct tape. It looked badass, but EWW! that must feel icky

Forget tape, just wear gloves.
It's like bar tape form-fitted to your hands.

Does mean that you give "street cred" to all the homeless ragamuffins who have electrical tape on their bars?

of coarse! j/k

gold duct tape = bling!!!

As anyone ever used duct tape to ,you know, actually tape/repair a damaged duct?

Actually they don't recommend it for that use anymore. I forget if it's an air-quality issue, or if modern ducts just don't work with it.

i hear electrical tape has a bit of lead in it, so I've stopped using it. I switched to gaffer's tape.

I recently noticed "Gorilla Tape" (by the makers of Gorilla Glue) at my local hardware store. Now that must be some badass stuff! Not recommended for use on Gorillas though.

I patch small gouges in my cork tape with Shoe Goop. It also works well for holding the bar-end plugs in place.

I used hot glue gun to do a "quick fix" one a big cut to my cork tape... that was months ago and its still perfect.

edit: in fact, its better than my grammar
