Old innertube sliced up and taped on the underside of my down tube. Looks decent. Well actually you don't even really see it. I taped it on with electrical tape over a year ago and it is is still there doing its job. Plain old electrical tape without the innertube works to but not as resilent and sound deadening as the innertube. I actually don't care about scratches and dirt, I just got annoyed with the constant pinging of debris.
