Vinyl Going Sticky

[Citroënbender]

I’ve read a little across the ‘net on this. Plenty of (no surprise) under-informed commentary.

What I want to know, is - for the softer vinyl used on B series Falcons and corresponding Territory door trim uppers/arm rests - what exactly is going on.

• Is there natural latex in the vinyl, that’s degrading?
• Is it a material that’s tipped over into an unstoppable state of chemical imbalance and will continue to break down?
• Is it caused by exposure to certain types of chemicals and the reaction’s byproduct can effectively be removed/stalled?

The reason I want to know, is in order to possibly glue microfibre “suede” over these materials.
