Are you thinking of "Never Slip Bait Tape" ??
http://neverslipbaittape.com/Tacklewarehouse sells it and it's promoted by Jarrett Edwards on his show.
They have all sorts of colors, and a spiffy package but it's a bit $$.
If you just want black or red you can get "Rescue Tape" aka "Self-Fusing Silicone Tape" online or at most automotive parts places (I get mine at Fleet Farm). Some Walmart's carry it back in their auto supplies section. It's a high temperature, self fusing tape used to wrap electrical connections. I keep some in my boat to fix stuff and use on my baits.
I use it a lot on wacky worms and to hold grubs on my bass and crappie jigs. It really does work well! I use black most of the time, but the red looks kind of like gills or an injured bait fish and a lot of people insist on some red on any bass lure.
