Problem Statement

Gluing rubber, such as EPDM.
Contact cement works on EPDM - [1]. Customer says this is 'closest to ideal' for EPDM on metal [2]
DAP 234 is essentially toluene, hexane, acetone with some dissolved rubber.
Dissolved rubber is polychlorinated rubber, the thing of rubber paint [3]
What is solvent of rubber paint? Toluene and xylene - [4]
Dissolved rubber - LionGuard [5] - for EPDM it's dissolved neoprene, in aromatics and ketone? Yes, same as DAP 123 (aromatics + acetone ketone).

Structural acrylic glues work - Permabond TA4605 and Permabond TA4610 structural acrylic adhesives - [6]

Wikipedia - CA -
Does not work well because it will stick, but contraction will easily break the glue - [7]
- -> Use rubbery (Styrene Butadiene Latex) solvent glues. Solvents soften the EPDM, styrene butadiene bonds.

EPDM is not neoprene [13]
Latex bonding agents - [14]. Latex is polymer particles in water.
- Styrene Butadiene Latex (SBL). See difference between Styrene Butadiene Rubber and Styrene Butadiene Latex [15]. Sourcing - [16] - 30% by weight SBL. 150-250 sf coverage. Can be used as primer for glue? Data Sheet - [17]. Sourcing - [18]
- Polyvinyl Acetate Latex
- Acrylic Latex. Ex - MAPEI [19], cement additive - [20]
Polyvinyl acetate is wood glue, Elmer's glue [21]
What is plastidip made of? Sorry sucka, that's secret. [22]
