I think the answer will lay with the type of glue or fastening method they used. Regardless of what kind, some discoloration might remain as the paint under the emblem would have 'aged' differently than the paint around it. The type of 'glue' may give you a clue about if the PAINT will adhere to the emblem or stay in place. Perhaps the question is best asked on the SPF web site.

I don't recall seeing that emblem on the pics of SPF's that I've seen? Was it discontinued at some point or do most people remove it right away?
