3m trim tape is very good. A few pointers though, Make sure the area your applying it to is completely dry and free from all contaminants dust grease etc also including waxes and polish, and then make sure you use a hair dryer (or heat gun further away) to heat up the contact surfaces both the bumper and spat, this gives the adhesive chance to get real tacky and then set once it cools giving it a more secure bond.
Just as a though but for extra security can you not add a few "hidden" pop rivets, underneath or the inside of the arch?
