Coosa Coring

Hey Guys,
I getting ready to purchase my floor material.
Do you think 1/2 Coosa will be strong enough for the floor.
Im going to cover with 1708 on both sides.

Thanks

I just put the fuel tank hatch on my 20 foot seacraft out of 1/2 inch coosa with 1708 on both sides It was plenty strong super light and the coosa will only absorb 2% water at most should water ever get into it. great choice and good luck.

Re: Coosa Coring

How many layers of 1708?
You may want to use the 1700 without matt, mat has no real strength just bulk Perhaps two layers 1700 on each side, with out the matt you will use less resin also.
I would use eopxy in lieu of vinylester or polyester resin.
You will get an incredible sandwich core with great strength.
