I think you might have the actual rules misunderstood or reversed.

Duct tape is nowhere declared illegal (though it was illegal for many years). As a matter of fact, I can find no declaration that any type of tape is illegal for any purpose (though using any tape other than electrical tape to insulate a connection is rather risky in terms of safety...)

However, contaminating a field element, which is what leaving sticky residue on a game piece could be considered, is generally considered field damage. (Lubricant contamination is specifically banned, IIRC.)

To answer the OP directly, you'll have to be a LOT more specific. You could try to use a roll of duct tape as a shooter wheel. You could try to use duct tape to hold the shooter together. You could try to use duct tape to affect the grip of the shooter wheel. I'm sure there are other potential uses. But unless you're asking something specific, we'll have a hard time helping.
