That would be Loctite 'Assure 425'....designed especially for low strength locking of plastic fasteners or metal fasteners in plastic assemblies. Its kind of blue also....Bacchus : Something I never really thought about a whole lot but, aren't all loctite compounds designed to be used on metal parts? Does loctite make a product meant to be used on certain plastics?? Just curious. Bake? My little engineering friend???
