Resin Tips

Always mix by volume unless the manufacturer specifies by weight
Mix slowly to minimize air bubbles; use a heat gun or torch to pop surface bubbles
Most epoxies cure in 24-72 hours; check brand specs for pot life and demold time
Temperature affects curing: 70-80 F (21-27 C) is ideal for most resins
