What is the difference between 3M 4200 and 5200?
3M’s Fast Cure 4200 has half the strength of 5200, which (with some effort) allows for disassembly of parts. A bond created with 3M 5200 may last forever, so you are in a pickle if you later decide to separate the two surfaces.

Will a 5200 PVC stick?
Solvents used with PVC, are to literally change the surface molecules on PVC, so that the cement (which really isn’t) can create a chemical weld. As to the use of polyurethanes like Sikaflex 292 or 3M 5200, you’ll not be as satisfied with the results, so wouldn’t be recommended.
