I'm in the process of cleaning and restoring my G1 Fort Max. I decided to fully disassemble everything and give it a thorough cleaning. All was going well until I got to the main body parts where I noticed some of the screws were so rusted, and that their screw heads were beyond disintegrated. I am now unable to proceed. There is one body screw that I need to remove to remove the main body halves, but I am challenged on how to remove it. Have any of you experienced rusted / rotten screws when restoring your vintage Transformers and were you able to remove them? Can Coke/Pepsi remove rotten screws? Would it harm the plastic?
