Will this adhere to a slick surface such as aluminum flashing?

Paint especially rattle cans don't tend to adhere to anything slippery, you must at least use something abrasive against it to some degree even if it's only a scour pad just to rough up the surface a little bit.

Would this work in the spare tire compartment located inside a cars' trunk?

Yes. Works pretty much anywhere

Is the undercoating product acid resistant?

I have no idea I bought it cove a mount for a fish finder. I didn’t like it it didn’t dry maybe I put to thick a coat
