I got a briskoda.net decal and I want to try to remove it and preserve it to put on the rear of the car, anyone got any ideas?

If its a vinyl cut one, then not a hope.

You may get it off by applying masking tape to keep the letters in place and heat with hair dryer to soften adhesive but then there will be no effective adhesive to stick it in the new location.

They're not that expensive so just get a new one.
