Help with oops

Better to strip it off or you might get high spots from the old adhesive.

you might try xylene. You can get it at the big box. For the future though, if the piece was laminated well the first time, a good sanding and removing the dust would of been fine to layer over.

I ended up using Acetone to remove the residue, then let it dry and reapplied the contact cement and then glued em together. Looks like the project was saved!! I guess the true test will be if it is still together five years from now!! Thanks!!!
