Puncture prevention fluid is a handy tool to use to prevent you picking up a puncture on your travels. It works by proactively filling any perforation in your tyre while you ride - however when a perforation is present, naturally some of the fluid within the tyre will be lost as the product works its magic. Because of this, it is necessary to keep your puncture prevention fluid topped up. We recommend reapplying an additional 70ml per tyre every 2 months. If your scooter has tyres which have an inner tube, you'll need to purchase a sealant which is suitable for these. A local scooter or bike shop will be able to help you here.
