Accumulator-I expect you to suggest 845 for waxing paint but plastic trim? are you for real? I never heard of intentionally putting wax on trim. I've done it by accident plenty of times though. I'm guessing IW doesn't stain trim.
Might sound weird but IME it works fine if you use the right wax (very important). Here are some specific examples that worked well for me:
-I've used wax (first Malm's liquid and then Souveran) on most of my XJS's plastic and even rubber trim since the late '80s.
-I used both 845 and 476S(!) on the exterior rubber and plastic trim of my outside 24/7 Volvo 245 wagon. Looked hideous whenever it needed redone but other than that it worked fine.
-I used the Klasse twins on the exterior plastic trim on my WRX wagon.
-I used 845 on the exterior plastic on my '00 Blazer after first polishing with 1Z Paint Polish. Worked great and that thing's trim was in pretty poor condition.
-I'm currently using both/either the Klasse twins and/or UPP spray on most of the black/dark gray plastic bits of my '01 S8 and my wife's '00 A8.
-I'm currently using the UPP spray on the plastic cowling at the base of the Yukon's windshield.
-I'm currently using 845 on the other black plastic trim on the Yukon.
-I've been using the Klasse twins on the '02 MPV's black plastic trim since new and it's stayed in great condition (like showroom new).
There have been a few cases where this LSP-based approach didn't work out:
-the black plastic foglight covers and sideview mirror trim of the XJS (not sure what's different about it compared to the rest of the plastic trim

)
-very worn black plastic trim on the Audi A8 (e.g., wheelwell liners)
-the black plastic covers on certain wiperarms (forget which at the moment, this is very rare IME)
So *generally* this approach works great as long as the trim in question isn't really worn down. Two specific instances where I do go the other route:
-On pieces that I *do* use a dressing-based approach (e.g., rear bumper/runningboard treads on the Blazer and Yukon) I use Autoglym Bumper Care.
-On my friend's '93 Audi the rubber around the sideview mirrors was *horribly* oxidized, and I mean it was really, really awful. I cleaned it up with Griot's Rubber Prep (super stuff!) and treated it with Ultima's trim stuff. This worked great and I'd feared that *nothing* would bring that trashed stuff back.
