Im pretty sure i read the same article, or one similar. There is a very
good article that compares using ethylene glycol only, or using some for
of
powder (forget what it was?) or a mix of the two, from the perspective of
later fibreglassing. It was well written. I would be quite content with
just treating the rot and painting the outside myself.
Infusion is just what i call it, some people call it injection and it goes
by a few other names. basically you drill the **** out of the rotten
section, and fill it with a special type of epoxy that soaks into the
wood.
You usually have to do this in several rounds, maybe 3. drill holes,
fill.
drill more holes, fill. drill yet more holes, fill. What you end up with
is ply that is totally impregnated with resin. This is an alternative to
cutting out the damaged section and replacing it. There are many good
writeups on this technique that give you the nitty gritty. You dont need
to
use reinforcing material, but some people do. This type of repair is
popular for areas like transoms. Commonly in the transom, after infusing,
people will add another piece of ply to the inside and epoxy together for
additional strength, then sometimes also add some woven mat as well.
Depends how bad your rotten section is. Some sections are easy to just
replace. So long as you scarf sufficiently and get a good bond, a
repaired
section can be stronger than new.
