How do I calculate how much resin I need?
To calculate volume in cubic inches: (radius squared) X pi (or, 3.14159265) x (desired epoxy coating thickness). Divide by 1.805 to convert cubic inch volume to US fluid ounces. To convert ounces to gallons, divide by 128.
Do I need to sand between coats of fiberglass?
There is no need to sand in between layers. Kind of. When a layer of mat has cured, there will be fibers sticking up. If these fibers aren’t knocked down with a quick once-over with coarse paper, they’ll create little air bubbles when the next layer is applied.

How thick can you pour epoxy resin?
As long as you pour in 1/8″ layers, you can go as thick as you like. The reason we recommend this thickness is two-fold: first, it allows the bubbles to escape properly, and second, it avoids any excessive overheating of the resin. So for best results always pour in a 1/8″ layer, and you’re good to go!Feb 6, 2021

If the Gelcoat that is applied at just over 0.5mm and 6 layers of Glass each 1mm, your laminate should be approximately 6 -7 mm thick.
