What epoxy is Best? I've had a lot of trouble with JB Kwik, lately.?

I used to use JB weld for everything. Lately, it seems it doesn't want to stick to itself. If I try to add more, say, if I find a leak or a void on hardening, the new epoxy doesn't adhere. I have to go down to bare metal and start again.

And, the JB kwik I've used (there are times I can't wait 24 hours or the stuff runs out of the hole) has just Crumbled on hardening. It's soft as plaster. I've tried 2 batches, months apart, same result.

Yes, I mix it evenly and thoroughly. I roughen the surface then clean with acetone.

Are any of those Super Epoxies (you know, showing a golf ball glued to a bottle) any good? I tried a few, they weren't as good as Original JB weld. I'm getting tired of spending more money trying epoxies than a new part is worth. Feel I should start my own website.

Yes, I've Emailed JB weld. I figure they owe me for a few bad tubes.

Update:

I've also heard of Devcon (the cream colored stuff) from Home Depot. I tried PC 7 , again, the stuff they show on a bottle, guess what? After 12 hours,like direcxtions say, Soft. I could push my thumbnail into it. And $7. I mixed it at 77 degrees , and as close to 50/50 as possible with a putty. and thoroughly.

I put the pieces in the oven at 150 deg. on a whim--They got Hard! But this is stupid. I shouldn't have to. And some pieces are, of course, too big to go in the oven. I think I might check CR at the library. I can't see resubscribing just for a few dollars of epoxy. I can get another clutch lever for $5 at a junker....
