Agree with Sunbeam--you need other structure with any epoxy. For example usually you build up layers of glass cloth with epoxy. You can also put a thickening agent in the other more brittle epoxies. I have only limited experience with G Flex--and that is working with plastics and other materials. Generally I don't use it with cloth, but that does not mean it could not be used as noted in the quote below from West Systems.
| Quote: | | A toughened, versatile, liquid epoxy for permanent waterproof bonding of fiberglass, ceramics, metals, plastics, damp and difficult-to-bond woods. With a modulus of elasticity of 150,000 PSI, it is a bit more flexible than standard epoxies and polyester, but much stiffer than adhesive sealants. This gives G/flex 650 the ability to make structural bonds that can absorb the stress of expansion, contraction, shock and vibration. It is ideal for bonding dissimilar materials. It can be modified with West System fillers and additives, and used to wet-out fiberglass tapes and fabrics |
My preference is to build a platform of glass cloth/epoxy (because of better secondary bonding than polyester) in the bottom of the anchor locker. You can then use thickened epoxy to smooth out and fill any irregularities in this floor. There should be little if any movement in this area--thus I don't believe the flexibility offers any advantage.
If there is a very small "hole" where moisture is getting thru--it would take some time for the moisture to show up in the bottom of the boat.
