Whenever I wipe off unwanted copper silicone off a metal yoyo, it leaves a weird sparkly and greasy residue. Does this happen with red rtv/blue rtv? brand is permatex ultra copper gasket maker.

No i’ve used red rtv for a while now and i have yet to do that happen. If it hinders your yoyo playing i reccomend using dry cloth or q-tip so it grabs the residue.
