I'm realizing that, MartinSr - and seeing as how a lot of the people I'm finding to subcontract the work to around here are old, or old-er, timers their "favorite products" range all the way from self-etching primer and lacquer, to red oxide as the best thing to put on a frame, to base-clear and everywhere in between.

MP&C, the self etching primer didn't have any immediate reaction with the areas where it was oversprayed onto the grey stuff and looked fine when I coated over it with equipment enamel 24-36 hrs. later.

FWIW my end finish materials will be Nason Fulthane on the exterior (over whatever this grey primer is) with Rust-Oleum farm/equipment satin black enamel brushed on the inside the tub (gets carpet so I just needed something to cover over the primer) and Transtar 2K epoxy primer on the sandblasted frame with the Rust-Oleum sprayed over that.
