I've seen this on the web here and there. Im guessing that it's some type of mild adhesive. If that;s the case, then I would be a bit afraid to use it. I dont think it's possible not to leave any residue after rolling it.

On Nagaoka website, I came across some interesting fact.
レコード針はLP両面をトレースすると、1.5Kｍ前後を走ることになります。
On a single LP(both sides), needle traces give or take 1.5km(0.94 mile) from beginning to the end.
