: I had problems with the 15 minute stuff until I figured out what I was doing
: wrong. I've had no problems since.

: 1. Even though it's 15 minute (5 in your case), it still takes about 24 hours
: to fully cure. I had my bungy straps for my hatch come off (after about 8h
: cure) because it hadn't cured long enough and the hot sun (in Seattle?)
: softened it up. I haven't had one problem with it once fully cured.

: 2. Roughen up (sand) both surfaces prior to bonding just like you would with
: the regular epoxy.

: 3. Make sure that the epoxy has a fillet around the outside of what you're
: gluing when you're all done. If the epoxy isn't squeezed out all the way
: around you'll have a stress riser under the part which is where it will
: start to let go.

: It sounds to me that you didn't let it cure long enough. Just because it says
: 5-minute doesn't mean it's fully cured by then. You just won't be able to
: move it around any more after 5 minutes. I personally like the 15 minute
: stuff because it's plenty fast enough and it seams to be pretty strong.

Ha! Ha! Thanks Dale :)

You just solved a problem for me with the 15 minute stuff as well. I was being really careful and letting it cure for a whole hour ( 4 times...should do it ) before bending a couple of pieces around. Broke every one at the joint. Major frustration. And of course... I didn't bother to read the labels. Hey, I know it all already....don't I? I was about to give up on that stuff forever. Thanks again. :)
