Building 1 time use mold. input?

[Dave Hirshberg]

Hi strict, and thanks
I gelcoated the inside with a brush and plumbed it with a stand pipe and a sureflow baitmaster mag drive pump and went straight out the transom with a stainless 1 1/2 thru hull drain. Using the Lenght times width times height divided by 231 formula it came up with 38 1/2 gallons. I was also able to get away with Gel Coat on the outside as well. When I matched the color to the boat I saved a pint and used it for touch up on the outside.
