I just bought a rear lip for a 2004 Audi A6. Its a 3m adhesive lips that you just lay on and press My questions is:

How do I align the rear lip to the contour of the trunk lid?? Measurements, templates?? any suggestions would help.

 

best way is to eye ball and test fit before removing the adhesive cover. use masking tape to align the corners and when you're ready then press it on. i dont think there's any templates or anything so good luck
