Picked up a set of NOS 67-68 rocker panel mouldings. One is absolutely perfect. The other still had the Ford packaging - paper back with clear plastic on the front side. The plastic on the front has some sort of glue, and it is coming off in small pieces - not too much fun. The glue residue however has me worried. Started with alcohol, then lacquer thinner, and xylene. Nothing really gets down all the way. Any recommendations out there? I will need to get a bit more aggressive, but don't want to go past the point of no return. Thanks.
