Thanks Simi 60. I'm thinking I'll put down layer(s) of CSM then woven cloth.
Didn't make any progress the last two days due to YC volunteering and the wx so I've been researching the upcoming steps.
Agree on using polyester resin. Found this on Fisheries website:
When building fiberglass structures using polyester resins, and where impact resistance is important, alternating layers of chopped strand mat and woven fiberglass cloth or roving will result in a stronger structure than using layers of woven cloth alone - which can delaminate under impact.
In this situation, the layers of mat bond to the woven cloth fabric better than the cloth does to itself.
As above, when using epoxy resins, only woven fabrics should be used for the strongest results.
When covering wooden structures - such as a wooden boat - with a layer of fiberglass cloth using polyester resins, you should not apply the woven cloth directly to the wood. Always start with a layer of lightweight mat - which acts as a binder between the wood and the woven fabric.
When cloth fabric is applied directly to wood, it can readily delaminate, whereas if mat is applied first, often the wood will fail before the mat can be peeled off.
Again, when using epoxy resins, cloth can be applied directly to the wood and result in a strong, permanent, bond.
I'll be filling some gaps in the frames with West Systems 610 and using Gel Magic two part adhesive epoxy to bond the ply to the frames.
With such a large surface area to cover the key will be working time and my ability to wet out well.
