Get some good quality 3M electrical tape. It's about 3 times the cost of the .89 per roll cheap stuff but it's much better. And there is also a trick to using the stretchy electrical tape. Get your first couple of stretched wraps onto the bars to hold the foam tape down and then leave a tag end about 3 to 4 inches long and cut it off neatly. Let the stretch shrink back out for a few seconds and then stretch only the first inch lightly as you lay the end on. The next inch goes down with a little less stretch and the last inch with no stretch at all. By reducing the stretch over the last few inches like this compared to pulling the end until it snaps you'll get almost no creep in the tape and it'll stay stuck down.
