Session Saver Instant Ding Repair Putty
Possibly the easiest ding repair ever.
Session Saver Ding Repair Putty works for polyester and epoxy boards, cures white, hardens in only 20 minutes, no sun required, and all without mixing or any mess at all.
That's because there's no hardener needed. Activation is caused by hand mixing.
