In the rare case of a ding, we recommend not repairing unless absolutely necessary. None of the components in Lib Tech Waterboards will absorb water.
We recommend using stickers, wax, hot-melt glue, etc. or anything to avoid polyester, epoxy, sandpaper and sanding. Dust and sanding sucks.
DO NOT USE POLYESTER RESIN.
Epoxy, and UV resins can all be used if absolutely necessary.
We favor epoxy for strength and safety. Never let any unhardened resin come in contact with your skin. Always remember, razor blades instead of sandpaper if possible.
