I have always broken parts when taking old kits apart but my son showed me the Z-7 Debonder for debonding CA glue and it works great on the old tube glue. I bought a 60 Plymouth that was probably built in 1960. I used the Z-7 and got it apart without breaking a single part. It had a roll bar glued to the back of the front seat and floor put Z-7 on it and in less than 5 min. took it out and wiped the glue off.
