What do I use to stick a "plymouth" script?

I would suggest the 3M double sided tape.

BUT since you mentioned you would rather not.

regular old black permatex silicone does and AWESOME job at sticking emblems down......only problem is, I hope you would have no plans of removing said badge in the future because once its on......its on LOL.

I used this method putting emblems on my recently painted car a few years back and then some time later decided I wanted to use a different set of emblems and when I tried to pull them off they wouldnt budge...after MUCH persuasion they finally came off......but......they took my paint with them .... DOAH:angry7:
