There is a type of Krazy glue that comes with a brush in the lid, I would use that.
Most modern car bumpers have been made with a specific mix that makes it almost impossible to glue. Many of these products are 'hot air welded' rather than glued.
Pin stripes.
Go to your local auto parts store and for about 5-10$ you can pick up door/panel trim glue. Reguler glue will gt hard and brittle and it will just falloff again.
6 or 8 it varies car to car.
Goof Off works well for this . I have tested it on 3 different cars and it didn't affect the paint finish at all.
Possibly if you could glue about 3 square feet of the roof to a pad from a crane.
Get a hot glue gun, glue the top, then inject hot glue into the bottom inside seam. That will hold, for awhile anyways.
Super Glue or duct tape
Funny! I have, personally, seen an advertisement of super glue, showing a car stuck to an elephant. Of course, this is just a technique of marketing, but you never know until you try it!

just use some scother tape, hade to do it plenty of times, will hold for a long long time
Pin stripes.
You get super glue and glue it in.
Blue, black, and red stripes look best on a white car
One may apply racing stripes to their car to give other people the impression their car is a lot faster than it really is. People who apply such stripes to slow cars get stereotyped as having a car with go faster stripes, sadly for the vehicle owner it is not the case.
Black or white stripes
You'd have to say a specific kind of glue.
