silicon gutter caulk
I used some silicon based gutter/flashing caulking in a corner of gutter. The old stuff was a very strong grey stuff most of which would not come off the gutter.
After a day of cure time the silicon stuff is dry but its rubbery not hard.
Is silicon gutter/flashing caulk any good? It says LIFETIME garuntee on the label, but usually that means the lifetime of a goldfish these days!
If the sucker leaks, what type of stuff should I use that I can get at a big box store?

Caulk should never harden, if caulking has hardened it's either past it's useful life or just cheap and not fit for use. Caulks are formulated to bridge a gap and must remain somewhat pliable to be effective.
IMO most anything in a caulking tube is caulk

I use gutter seamer mate, gray stuff on gutter components. Never leak. Sticks to everything, so be careful. Amerimax Home Products 10 oz. Gutter Sealant-85148 at The Home Depot

Pure silicone will degrade in sunlight. Some use acrylic silicone, but I prefer to use a product that has proven to tackle the problems of a specific area. The seamer mate is one of those products.

Seamer Mate seems to be some sort of butyl rubber maybe and would probably be a good choice. Trust the man who uses it on his jobs I say.

Is Silicon used on gutter seams though? I simply bought the tube that said gutter and flashing silicon .... now you guys are making me want to pull it all off and use the Seamer Mate.
ok, what do the gutter dudes and roofers have to say about this?

There is no need to pull it all off. If it is on and you have covered the seam completely and there's no leaks it would be silly to get right back up there and fool with it again. Re-evaluate your choice of sealant when you see leaks and it's time to re-do it. That time will come no matter which sealant you use, just a little sooner for some.

I cant win.
I thought I do another corner, since I ran out of the silicon I used on the other one a few days ago I picked up the seamermate. No sooner than 3 hours after applying the seamermate to the gutter it started to rain. So my repair is underwater and uncured.
It says on the seamermate bottle that it cures underwater.... I doubt that, but we are putting it to the test I guess. I went out during the rain and my leaks appeared to have disappeared though despite the rain!!!
