Someone on the list, I can't recall who, made some test samples to see if
epoxy would stick to the paper. In each case the wood failed, not the
paper. I know that this sounds like a friend of a friend told me but I'm
sure that it was on the bolger group.

I used the MDO (single overlay, not both faces) , but on the side with the overlay ( interior of the boat) planed off the overlay anywhere a structural joint was to be made (stitch and glue fillets and tape) . Flat surfaces were going to get paint so were just epoxy coated and painted. . Outside was fir plywood surface with epoxy / glass sheathing.

Remember the MDO is wasted on a surface which is to be sheathed. It just gives a smooth check free surface for the paint. If the whole thing is to be sheathed, use fir marine ply or other.

While everyone seems to have great results, I wouldn't be inserting a
layer of paper between my glass/epoxy and the underlying wood. I
can't see why this would be good. I don't know what is in the paper,
or how well the epoxy will bond or penetrate. With these products
what is the guaranteee that all will be prepared similarly. That
isn't a rewarding conclusion with other ply products.

The MDO I used was covered in paper which was not saturated with glue
but glued to the wood. The glue survived boiling but you could peal the
paper layer off. The paper layer readily soaked up water and soaked up
epoxy like a sponge, about 5 gallons. In fact, I could coat it with a
liberal coat of epoxy and five minutes later large sections of it
appeared dry so I would have to recoat minutes later. I dont think the
epoxy penetrated the glue layer into the wood. It did produce a very
tough outer layer of epoxy/paper about a 32nd of an inch thick. If I
had it to do over again, Id just use luan for the sides and top and b/c
fir for the bottom.

Garth - there is a ply FAQ on John Kohnen's site. The link is also
available from the Cheap Pages (URL below) - the search engine is on
the first page.

Th3e short answer is "make sure it's clean" and otherwise you should
have no trouble.

MDO is good wood. In the 18 month's I've messed with it, I've found ONE very small void.

While everyone seems to have great results, I wouldn't be inserting a
layer of paper between my glass/epoxy and the underlying wood. I
can't see why this would be good. I don't know what is in the paper,
or how well the epoxy will bond or penetrate. With these products
what is the guaranteee that all will be prepared similarly. That
isn't a rewarding conclusion with other ply products.

Yes. No. (except for looks, maybe)

I rummaged around in the archives of the group but couldn't find the
answer to my question: Does epoxy bond well to the paper-and-resin
side of MDO? Do you need to sand it down or prepare it in any way to
make, say, a glass-tape butt joint across two pieces?

All best,
