: i am restoring a cedar strip with a bit of wet rot. it is drying. the lay up
: are will be 20 feet x 45 inches at the widest section. i will be using
: epoxy. have yet to decide if a layer of 6 ounce kevlar will go on first,
: or two layers of 6 ounce glass. i've been told to lay one whole piece-45
: inches, the whole length. then move right on to the second layer. is there
: any reason not to lay two halves, overlapped lengthwise? this will be
: easier to do alone. can anyone advise, one piece over halvsies? i have a
: space, radiant heated, more or less 65 degrees, dry, (northern mn,
: december)to work in. timing will make it difficult to have help on the
: layup.

First, the rotted wood will have to be replaced, just drying it will do nothing to the rot spores and it'll continue to spread if not removed. Next, you're thinking way too much cloth, 6 ounces total is common and no kevlar, does little except add alot of cost to a wood strip boat and likely will add weight, it's very hard to tell when kevlar is wetted out so you end up with too much resin.

If the glass is applied on a slight bias, weave not parrellel to the keel, it'll drape easily and you can do it with a single piece, it's not all that difficult to work both sides sorta at the same time. Epoxy takes quite awile to set up fully so you have plenty of time to lay it all up at once.
