Have a look at Plastic Glue deluxe by Rocket.
I think you mean Plastic Magic by Deluxe Materials, who make Rokit super glue. I've used the plastic glue and found it effective, but switched to Tamiya Extra Thin Cement after finding the DM product, for some reason, utterly hopeless for making sprue goo, which I now find indispensable. Rather than the paste I was looking for, dissolving sprue in PM resulted in a rubbery blob that is almost impossible to extract from the jar and, if extracted, has no use I can think of. On its own, however, the glue is fine, if not as fast-acting as Tamiya Extra Thin.
