Re: how many layers?
Ref: The fiberglass boat repair manual Allan H. Vaitses
This is my plan mat(2)/roving/mat/roving/mat/roving/mat for my boat.
I am in the planning process.
I first will place the resin on the stringer then the mat.
mat 1.5 ounce
roving 24 ounce
By the way what are you using for the stringer?
Hardwood, softwood , foam, marine plywood?
