It may be worth noting that there are actually two different readily-available "super glues" in the non-specialist arena: methyl cyanoacrylate and ethyl cyanoacrylate. Most of the common super glue is methyl CA; ethyl CA is most often sold for attaching fake fingernails.

Monty Ohren, the very experienced slot racer who runs the Best 'O The West motor blueprinting service in California, has indicated that the ethyl CA works better for gluing magnets into 1/24 motors. It seems to stand up under the thermal loads better, he says.

Here's a link to one company's specifications sheet for both types of CA:

Hi-Strength Super Glues

(This link is to a PDF file, thus Acrobat Reader will be needed: www.adobe.com.)

There is a lot of good information about methyl and ethyl CA in this PDF. There are differences in the properties of methyl CA and ethyl CA.

BTW, the cosmetics department is the best place to find ethyl CA. Just be certain that "ethyl cyanoacrylate" is listed as the ingredient, not just "cyanoacrylate." I've had no problem finding multiple brands of ethyl CA alongside the plastic fingernails here in the US.

There is one caveat about storing CA in the refrigerator. Quoting from the PDF I mentioned:

"Cyanoacrylate adhesive must be stored under refrigeration at a temp of 40 degrees F (+/-5%) for maximum shelf life. Before opening, the container must be warmed to room temperature, otherwise water might condense into the bottle and cause hardening of the adhesive."
