I have a truck camper that is over 30 years old. Some of the plywood
in this camper is weather checked and/or rotted. It's 3/4 inch
plywood, and I don't know if it's "treated" or not.
The wood is dry.
The rotted areas are exposed to the sun sometimes.
I am soon going to sand the surface of this plywood.
What product or products would work for me to brush on this wood? I
want to stop further deterioration, and also give some strength to the
rotted areas. I'm not too concerned with the cosmetics of this plywood
after this operation, but _AM_ concerned about giving or restoring
some structural strength to it.
Replacing the plywood is NOT an option.
Thank you....... Lee Carkenord
Why is replacing the plywood NOT an option? That's really your best route.
You could apply a coat of fiberglass over the bad areas, making sure to
reach out on to good wood. Apply it per the directions and paint when done.

Then you have no option.
Once dry rot has set in, the only option is replacement.
Well, if he glasses over the affected area he can achieve a repair of sorts.
Not as good a plan as replacing the wood by any means, but a decent glass
job will effectively seal the wood against air and moisture - to the point
that the wood is only subject to its normal rate of absorption in the
surrounding areas. The glass will span an area with suitable structural
strength, but that span is obviously dependent upon a couple of factors.
The OP never mentioned the size of the affected area so it's hard to suggest
just how well a glass repair would really work.
I know that if it were me, I'd replace the wood. It's going to be less work
in the end than doing a proper glass job. For some reason he feels
replacing the wood is out of the question. Not sure I understand that.

You have no chance at all with polyester, woven roving and mat.
You might get some benefit using epoxy and double bias knitted glass but
Either of the above is moot if the cost of replacement 3/4" ply is a
Either of the above will cost 2-5 times the cost of ply.

Sheesh ... don't they teach anything in school anymore?
Gluvit or similar. Not cheap and (like all epoxies) needs to be painted
to protect it from UV light.
How much strength you could get with just Gluvit depends on a lot of
vartiables...mostly, how big the area is, if it is rotted through and
what kind of structural strength you want. If you are talking about
smallish areas and just want to plug them up, Bondo.
That camper will come off in the first real side wind that you
encounter. Please take it off, cut some fire wood, trash the rest and
buy a new one. I have seen one come off and read about others. Water
damage and termites will kill you.
