Extra protection stuff?

[dimsum69]

Hey everyone!
I just purchased a yaris today, and it will take a few weeks to get it
I live up in Canada and here they offer some "protection" stuff at the dealership
Highest package is about 1500 and comes with:
Undercoat Protection (Black tar stuff to stop underbody rust)
Rust protection along door jams and wheel wells
Paint protection (A long lasting wax/clear coat they claim)
Interior protection (Fabric Spray)
and 3M tape for the hood and bumper

Anyways, I've been told mostly dealers mark the price up and outsource anyways so I'm expecting to be ripped off money wise thru their program. However being in Canada, and we get snow and this city salts from time to time, I wouldn't mind getting the Undercoat protection, cause i guess anything helps.
All the paint stuff, I'll just wash and wax and I know i'll be fine. Interior will be easy to maintain.

I guess my biggest question is if anyone got the 3M stuff? My yaris will be that new pearl white, but my last car had 3m tape on it, and after 3 years it started to yellow just a tad. I dont like chips, but I don't like yellowing tape that, if replaced could peel the paint anyways.. Has anyone got a white yaris and the 3M tape with any review?
Any info about these would be great anyways! Thanks for your time!
