Using the 3M moulding tape to retape an emblem, esp a series of letters, is an exercise in futility. It is extremely difficult to cut the adhesive w/o some of it showing around the edges. You often have to use two strips of moulding tape and anywhere there are gaps, there is a tendency over time for dirt to infiltrate and cause the emblem to separate from the tape. The correct procedure is to have used a release agent on the original emblem so as to not damage the backing. Then use clear emblem adhesive to reglue. This glue, however, will damage paint. The short response is to just buy a new emblem.
