"Shelf life of WEST SYSTEM epoxy is several years."
That certainly nails it down, doesn't it? ;-)
My only problem has been the pumps going bad when stored for too long.
Once they go bad, you can't get the mix ratio right because they won't
prime correctly and they just sputter and drip. If you toss them, you
end up tossing some of the product too and the stuff ain't cheap.
If it is more than $21 then I'd be at a net loss for the past 30
I did buy a couple gallons of West years ago when I built a couple
Bolger boats. If I ever build that strip kayak I'll probably get
some more. But in the meantime- JB weld works just fine.
Had to look it up- 1 gallon West +hardener= @$120
1 Gal US Composites epoxy +hardener- @$70
until I have a specific job, I think I'll get by with the tube of JB
weld on my workbench.
Look at all that money you're wasting! Buy a gallon and it's less
than $1/oz!! So you don't use it and have to pass it on to your
great-great-great-great-great.... Nevermind. With all these toxic
chemicals lying around waiting for someone to use them, I doubt life
as we know it will exist that long.
I use the uscomposites 2 to 1 epoxy. http://www.uscomposites.com/epoxy.html
It's slow enough to provide a good bond and the 2 to 1 ratio is easy
to achieve for almost any size project. I'm not in a hurry. I buy it
by the quart of resin. I also keep a few fillers on hand.
http://www.uscomposites.com/fillers.html In some cases I just use
sawdust or talc powder. This covers me for most requirements. A
quart is $24 and lasts me a long time unless I use a lot for something
on the boat.
I see that the prices for the USc products are cheaper than the West
Systems on that site, but I'd need to factor in shipping to see if it
still comes out cheaper than what I pay for West Systems at the local
I haven't seen the USc products on the shelf, but it might be worth

There's no argument that JB Weld is much more expensive than West
Systems (or many others).
However, I'm not going to pull out my pumps, mixing cups, stir sticks,
etc. to mix up a tiny glob of epoxy.
If I did, I'd have to factor in the cost of the waste since I couldn't
reliably measure such a small amount like I can with the 1:1 ratio of
JB Weld. Eyeballing a 5:1 ratio of 2 liquids is a little tougher than
a 1:1 ratio of 2 pastes.
I guess I could look into West Systems G/flex, which has a 1:1 mix
ratio, but my gut tells me that it's in the price range of JB Weld.
Oh yeah, one more argument for the use of JB Weld that hit me last
night as I tossed my tool box in the van:
I usually have the baggie with the JB Weld and toothpicks in my tool
box. I don't bring my "milk crate West Systems epoxy kit" with me
unless I know I will need it.
On a recent job, I had my portable air compressor with me. The
"handle" for the petcock on the tank fell off. I mixed up a minuscule
amount of JB Weld - right then and there - spread it around the
petcock and taped it in place.
I would have wasted a lot more time and product if I had waited until
I got home and mixed up some West Systems. Heck, I probably would have
lost the petcock handle by then. ;-)
Expensive, sure, but d*mn convenient.
re: "I don't do any of this for a living, all my work is diy"
Same for me, if by DIY you mean the kid's houses, the parent's houses,
volunteer work and hobbies that require the work be done away from the
That's why having some JB Weld in my toolbox makes more sense than
hauling around my epoxy kit. I was 350 miles from home when I needed
(OK, *wanted*) to fix my compressor. Trust me...I would have lost the
part by the time I got home 4 days later. ;-)
re: "Now, if I could only find an equivelent to the old non-mixing

You mean something like:

OK...the last one might not be exactly what you are looking for. ;-)

re: "Epoxy that sets in 5 minutes..."
JB Weld does not set in 5 minutes. JB Kwik might, but not JB Weld.
JB Weld is 4 - 6 hours to set, 15 to full hard (more or less)
Granted, it's not as versatile as something like West Systems and all
it's related fillers and stuff, but when I need just a dab of Epoxy,
JB Weld is pretty handy.
I've got an old piece of stiff plastic (1/8" x 4" x ~2') leftover from
some project that's dotted with dried up blobs of JB Weld with tooth
picks sticking out of them. It's my favorite mixing board.
