Anything Crucial like that ,
preferable to pre coat BOTH mating surfaces .
Even if ones scraped back to just damp , it ensures a complete join,
whereas with just one coated , dry spots ( unglued ) are pretty much assured, no matter how salubrious you are .
Dunno if this is possable with super glue ?? Would yo use the GEL type / thick there ? and its slower kicking off ?
