The trick to superglue is to use the right kind for the right situation. Copied from an earlier thread:
I just wanted to add some thing about super glue. In my experience, brand isn't actually important, but every hobbist owes it to themselves to have 2 (possibly 3) kinds of superglue. I've given the BSI names below, but other brands make similar products.
1) A thick or "Gel" superglue (Maxi-Cure) for:
-gap filling
-joining of parts that aren't evenly matched.
2) A thin watery glue (insta-cure) for:
-Instant attachment of porus materials like balsa,
-surfaces that are well matched and need a close bond
-Strengthening of existing bonds. A truely thin superglue will be sucked into an existing crack by capilary action.
3)Optional: A ruberized (
IC-2000) or flexible (Instaflex) super glue
-For gluing heavy metal models without pinning.
-For gluing models where shock absorbtion (usually heavy metal models) is a concern.
All 3 kinds of glue can be found from Bob Smith Industries. If you've never noticed BSI glue, it's because it's probably the brand in your model shop with the model shop's name stamped on it. Usually BSI glues are very reasonably priced. BSI ruberized glues are a bit less common in shops, but Gorilla rubberized glue is fairly widely available at hardware stores.
You can see all 3 kinds of glues here:

Sum up, glue type matters alot. Buying Loctite, Gorilla, BSI, or Krazy is no guarantee of good results unless you're buying the right tool for the job.
