pssstue - Glad to hear you're leaving off the "glue only" badges. *I* think your ride will look a LOT classier without them :xyxthumbs
As far as reattaching the center one, *NO*, I did *NOT* mean solvent=AIO. Sorry to be so emphatic but I don't want you to mess this up due to misunderstanding. AIO will leave a (somewhat thin) layer of synthetic "wax"/protection on the surface that would compromise your adhesive's adhesion.
I meant a "real" solvent such as PrepSol, 3M Adhesive *REMOVER*, or some other "paint prep" product. Maybe you could get by with rubbing alcohol.
OR, maybe you could get by with NO ADHESIVE AT ALL, relying on just the mounting pins. I have several vehicles whose emblems are ONLY held on with the pins and they're just fine. Maybe a little dab of RTV sealant or badge adhesive on the badge's pins when you pop it back on. :nixweiss if it would work for you, every situation's gonna be a little different, but it's worked OK for me.
