Does Insta-set actually have a glue? From the quick google search I just did Insta-set seems to be only an accelerator.
Most of us use whatever brand we can find of CA GELglue. It is the 'gel' part that is important. ICGel is a popular one as well as some brands sold at Home Depot and CVS. I'm sure others will jump in with their formal names.
everyone is right, loctite can be purchased at home depot, but read the ingredients for cyanoacrylate. IC gel is by far the most glue for your money, but I could only seem to find it online, never on the shelf. If all else fails, krazy glue works also, but it sux. :shhh:
