 matter.

Cliff,
I buy the stuff from an epoxy supplier (mostly to the boatbuilding trade)
here in Seattle called SYSTEM THREE EPOXY. They make all the standard cure
speeds.

I like supporting a local company, but mostly I buy it because of the
packaging. 5min epoxy, to me, is all about convenience. System Three sells
their 5min in a pair of 6oz squeezable bottles (bigger too, if you're really
gonna go through the stuff) with nice spouts that don't leak, and caps that
are color coded to their bottles and super easy to get on and off. I can
have a batch of 5min mixed up faster, cleaner, and neater with these bottles
than any others I've tried.

And I trust the brand, having had much good epoxy experience at several of
their different cure speeds, though mostly not on model airplane projects.
One project I did is almost 10years old, full outdoor exposure, and holding
up really well. I don't know exactly how they stack up price wise, but I
gotta assume they're competitive or better with anything else worth buying.
Don't know how good their mail order service or shipping rates are, as I
just pick up the stuff I need at their shipping office which doubles as a
direct retail outlet.

Can get you a number for System Three if you're interested. BTW they also
make a two part expanding foam product that is pretty impressive. Makes
polyurethane foam at 2lbs/sq foot, when fully expanded. Don't know if it
really has any uses in model building, but Yee Hah, does that stuff expand!

Lift,
Scobie in Seattle.

Hi
Most 5 min epoxies don't have as much strength as 30  60 min
epoxies. But most of the epoxies from the Hobby Shops are for
general purpose applications. I like to use Hysol Adhesives 
they have epoxies for specific use.
But their are other ones that are good too.
