Default Shelf life for glue (revisited)

I have Weldwood Plastic Resin glue, Elmer's carepenter's glue, and
Elmer's resorcinol glue that are old. None give a shelf life on the
container. I think I saw 1 year for Plastic resin (a powder). In any
case, all have been used long after they were purchased and continue
to performed as expected. There is no reason to believe that glue
will fail some time after the application if it doesn't fail
immediately after or during application. All glues probably fail over
a period of time and under adverse conditions.


From the age of 17 to 40 I was in the automotive business and retired at 40
from upper management. To keep my sanity during those years I took up
Woodworking seriousely when I was 23. I puttered around with it since I was
10. Now I am self employeed, dont have to work but choose to. I design and
build custom furniture or just about anything wood related including
repairing furniture. Almost always the furniture fails because of the glue.
This furniture that I work on ranges in age of 60 years old to 4 years old
and all in between. For me, there is a reason to believe that glue fails
prematurely.

The world is so full of crap about products and applications that it
is difficult to know what is true, but some is such obvious bull****
that you wonder why people believe it. As an example, periodic wheel
alignment. Wheels are either aligned or not, and the only way to
become unaligned is to bend, break, or wear out a part.


Taking into consideration my previous profession, I tend to agree with your
observation. More often than not, a symptom that indicates the need for an
alignment is a bad tire. The tire can be brand new and still be bad. That
said, if the nuts and bolts that tighten the tie rod end sleeves loosen for
some reason or were not tightened properly, a pot hole in the road can knock
the alignment out with out necessarily damaging any front end parts. I do
not subscribe to periodic wheel alignments unless tire wear indicates the
need. Simply having the alignment "checked" is a good idea when having new
tires mounted. The caster or camber can be out of spec's and will cause
premature tire wear and not necessarily be noticed by a pull or drift of the
vehicle.

If you don't
need a new part for the alignment then you didn't need an alignment or
more likely it wasn't aligned correctly the last time.


That is normally true.

Because some things do need periodic maintenance and some things do go
bad after a period of storage, it is easy for manufactures to prey on
the gullible by insisting on certain periodic maintenance and on
replacing older products.

A 1 year or six month warranty (or shelf life) is probably more about
legal protection and a desire to sell more product than any truth
about the product.


Yeah, like you said, probably, but maybe not.
