For on-road ease of flat repair, I've sealed my rim to use tubeless rubber on my F8GS. EDIT: Thanks!!! to Cyborg (his link) (Finally found the link...) Supplies Prep Conversion "Seals All" went into the syringe. Goop went directly from tube. Apply two layers of Seals All. Wait 30min then apply one layer of Goop. Let stand over night. Remount.
