I used Greenlight's resin chart a bunch of times while glassing boards. It's a great resource, but I wanted to make it easier to use. So I built this calculator to help you figure out how much resin you need for your next glass job. Welcome to Surfnerd's Resin Calculator! If you're ever in a pinch, wondering just how much resin it takes to perfect your surfboard, you've landed in the right spot. Looking for a good forecasting app? We've got that too!
