Repeat what was said to you to the managers / owners of the shops you talked to, then hand them a printed copy of the clear, concise statement sinned posted above and see which one he/she agrees with.

The only thing I would do differently is to DA the surface smooth first, then use a chemical wipe to etch/clean the plastic surface.
