Here is a small amount of Resin Research CE/2100F to do ding repair. Eight (8) ounces of Epoxy and four (2) ounces of Hardener. The Resin Research CE/2100F is perfect for ding repair as it goes off quick and becomes hard faster than most other surfboard epoxies on the market. This epoxy has a slight blue tint which is the common epoxy used in manufacturing. The blueish color will go away as the resin is mixed and applied to the board (will not affect pigments or tints! It is made to be used as a 2 to 1 ratio. Great for ding repair or when you don’t want to buy a whole quart!
