If the rear glass is the same as the 94's, the mirror shine will remain. The only difference will be that you can't see through it from the outside. I put 20% on my rear glass with the factory mirror tint and I cannot see into my EX at all from the rear, but can still see out very well. And yes, the rest of the windows should just appear darker. You really can't always go by what is on the package for the "bronze" or "mirror" tints.
Although under normal circumstances I would not recommend using their brand (simply because IMO I feel there are better quality films, but with the explorers, most are of us are trying to match the factory mirror tint) Walmarts highsest quality film does not say bronze or mirror on it, but it does match the factory "mirrorness" very good.
This may be more info than you needed, but FWI.....
