I don't really know. I am not sure I even know how to use it correctly. It seems to be like liquid steel on some of my projects and other times it literally falls apart with slightest touch.

Agree with @Toby. Every time I use it, I am at least successful at gluing my fingers together. Other than that, I actually read the directions on how to use it the other day... and learned that you are supposed to put super glue on BOTH surfaces that you stick together. Who would've thunk?

The only time I've ever seen superglue do anything was when working on lead/pewter D&D miniatures. I'd drill a tiny hole and use superglue + a small pin to attach limbs that weren't pre-molded on. Anything other than that and it just didn't work.

I mean, it works *great* on my fingers, but that's not listed on the packaging.

my fingers and superglue are made for each other! other than that it seems to work on everything ive tried it on. I think the biggest thing for me is to use the right amount. I always seem to error on using too much and then regret it.

It's good with certain types of plastics, foams (like EPS foam used in RC airplanes, and balsa wood. It's bad with metal and other types of plastics.

CA was originally developed to be used as a replacement for emergency sutures, aka stiches, so it definitely works to adhere skin to skin... or to whatever you happen to be touching when the glue is still wet. (oops!)

But my real "do all" adhesive when I need a good bond is JB Weld... .

I had good luck repairing a broken tab on a 1541 pressure pad holder with the CA + baking soda trick. I used the repeated dipping method to build up a new "peg" around the old stump, and with a bit of filing and sanding it plugged in tightly to the pressure pad arm. No trouble since.

CA can be difficult to use on plastics because it doesn't form a chemical bond with them. You need a mechanical interface - a sand-paper-rough surface - or a lot of surface area. It's brittleness makes it impossible to use in places where you need to withstand flexing forces - it either needs to be absolutely rigid or it won't work at all.

Baking soda/CA cement however is much tougher in that respect.

It doesn't bond some things, and yes it is brittle and shatters when in a flexing situation. It makes a great bond in conjunction with other things though, and on surfaces that it can bond to, that don't flex it works great. I have long ago given up on it being the "super" top glue for every use, anyone who believes that myth will be let down by it. I always keep a bottle around, and use it fairly regularly. I don't suggest believing Bondic is the new super amazing glue, but it has good uses too just like anything else.
