I may have left what little wisdom I have at the door here, but has anyone used this to fix a frame?
seems rather too good to be true, so it probably is!

Can't answer your specific question as I've not used it. But brazing is not going to be as strong as the original part. And given your original part was already not strong enough, then I don't think this will last long.
Same could actually be said about a weld repair on aluminium actually.
I might be wrong though as I don't exactly know what you're trying to fix.
Don't think I'd trust it. Alu is a bugger at the best of times so if I was trying to fix some thing I'd get it done properly.
Well not that I have anything in particular that needs repairing, but many years ago I had to chuck an old marin nail trail frame that had cracks in the headtube.
Just wondering if anyone had actually been brave enough to try it really.
and it makes much more sense to get it done by someone who know's what's up...
Shame, could have been fun. "Welcome to Benny's frame shop", comprising blowtorch, JB weld and a lump-hammer.
I've used similar to fill a tyre groove in a five swing arm.
It is far harder than the surrounding aluminium once it has cooled so you need to be quite neat whilst applying.
I did also have a play at jointing some scrap - I couldn't separate the two bits once joined...
But probably not as good as an AC tig set!
I used some in the past to fix a leaking alloy petrol tank on my cafe racer. It worked ok but not as well as a properly welded joint.
If it's a structural part then I wouldn't use it.
