I have always noticed that my front bumper is a slightly different color than the rest of the car. Is this normal? Also what do you suggest I can use to fix this crack?
FYI... my bumper had that same exact crack in that same exact spot - only on both sides, to make matters worse. Opposite this crack is a “clip” as it were, and it helps keep the bumper affixed and stabilized. Since this is a stress area, incidentally, the whole “clip” will eventually break off, and this crack precedes this event.
If I were you I would strongly recommend using some type of crystal clear Crazy Glue or epoxy to keep this piece in place, because once the piece separates and flies away, it’s quite unsightly.
