Hey all, I picked up a used set of rock warriors on FB for 700 bucks and when I got them home I noticed a hard ish substance around the valve stem. I feel like an idiot not thoroughly inspecting before paying, but I peeled some of it off and don’t see any cracks underneath nor any cracks on the inside of the rim. Chat GPT says it could be bead sealant, anyone got any ideas? Is it a concern?
