Well, now I've went and done it.

I've got some Tomahawk coming as it had great recommendations also, and it was the 1st material I found when ordering. Have to say, even though I ordered on the weekend, I called the 1st thing this morning to try and add another rod to my order and it had already been put in the mail. They are a 1st class operation for sure, great service. Now I just have to wait for the epoxy as the stuff I had I didn't like as it took forever, days, to cure. While I'm never in much of a hurry, I would like to be able to work it the next day.

Pretty much all epoxy is fully cured after 72hrs. The 5-min, 1-hour, 24-hour ratings are based on a percentage of full strength. If the epoxy was still liquid or very pliable after days, it is either bad or you didn't mix properly (ratio or not actually stirring enough).

It was that JB welded clear 5 min. I used it about 5 times on that project and after the 1st time not setting up I was real careful.
Must be bad as it took almost 3 days to firm up. That's why I ordered some different stuff for now.

You need a epoxy that suitable for the job. 5min epoxy, regardless of the brand is junk! Use a slow cure epoxy. Get a scale that accurately measures small amounts, lay a playing card on the scale, power it on, weight out equal parts of the epoxy (or whatever ratio the manufacturer recommends.) and thoroughly mix the epoxy, this usually leaves the epoxy slightly cloudy.
I always make a point of saving to the playing card with the epoxy leftovers, so I can check that the epoxy has properly cured. 24 hours is usually enough for it to set up enough for use, but for something like a basecoat, I always wait 72 hours before sanding. If the epoxy comes off in small lumps, it's not cured, it should come off as a fine white powder.
 
I've used epoxy for years and never had an issue till this last time. My other epoxy had got old so I went out and all I could find was this stuff and didn't want to wait to order some longer cure higher strength stuff. It was just an experiment I was doing on something anyway. It just didn't fully harden up and was slightly tacky to the touch the next day. After about 3 days all was fine, but that was it for that stuff, never had that happen before. I'm fully familiar with letting things cure first before sanding as I have a very extensive woodworking background. I've ordered some new epoxy in a couple different cure rates. Thankfully all this playing around has been on my own stuff.

I had this recently happen to me about 2 months ago. I used it to glue something together and the next day it was rubbery. I look at the bottles and one has a cloudy bottom. They were new bottles purchase earlier in the summer.

I use T-88 and it is a 24 hr cure time. It works VERY well, not cheap but worth it.
