[bolger] Re: CPES (was Jochems Exposition)
- About CPES, at the risk of touching off ANOTHER endless discussion (but that's
what we're here for, ain't it? ;-) ).....
My horse's mouth that I have my info from are the folks at Smith Brothers in
Richmond, CA, who makes the stuff, along with some communications with Dave
Carnell. Basically, it's very, very thinned out Epoxy. The advantage of it
being thinned out is that it wicks into wood, blocking up the channels in which
mould (rot) ordinarily grows and creating a moisture barrier that kills (dries
out) any existing rot. Basically, for a price, very hefty price in some cases,
you are turning wood into a wood/epoxy composite, not bad, but is it worth it?
That's for you to decide, obviously it's THE STUFF if you are restoring
rotted-out wood, but should you pre-emptively slop it onto a new boat? Up to
As for "will it turn cheap plywood into good plywood?", in a word, no. It won't
cross glue lines, so you'll just be "epoxyfying" the face plys (at great cost),
which don't buy you much. It won't fill in interior voids. Of course, Smith
Bros. recommended it to me anyway, the idea being that "epoxyfied" outer plys
would completely seal off any rot-forming interior voids... the costs come out
to $60 or $70 per 100 sq ft (and remember that you'd have to coat both sides of
the plywood..so double the price, ouch!) by the time you're done screwing
around, you may as well just buy good plywood in the first place.
- Thanx for the tip, Gregg. Your advice helps lean me more in the direction I was starting to lean anyway (toward good plywood). The quest for "good" prices in Atlantic Canada is now my real challenge.
- Thanks, Jack.

The quest for "good" prices in Atlantic Canada is now my real challenge.As a *real cheapskate* this is a hard lesson for me to learn. The older I get the more I am sympathetic to buying better stuff (tools?) and being done with it, rather than buying cheaper stuff
(Craftsman?) and either suffering or taking time/a lot of time to improve the marginal product (AC fir plywood?).
