mirror help

my rearview mirror (or whatever you call the mirror stuck on the windshield) fell off. I'm assuming its due to the heat and humidity lately. Where can i find adhesive to put it back on and what kind should i use? Do i need to scrape off the old adhesive, if so how? Thanks for any help.

ps. is it illegal in pa to drive without said mirror?

Go to your auto parts store and pick up rearview mirror epoxy/adhesive. Yes your going to have to scrap off the remaining adhesive.

yes it is illegal to drive in PA w/o the rear veiw mirrors; all your mirrors; turn signals, horn, brake lights and headlights must be in working order.

ya its illegal to drive with out your review any where, so get that fixed right away
