I had put in a front air dam, and the dealership forgot to put the front rotary crest on.
They just sent me the old one. I installed it with with the old sticky tape inside.
One edge of it is slightly loose, any ideas on what I can stick in there or glue to secure it. Thanks!!!

 

Use 3m double sided foam tape. (a body shop supply store - or even your local bodyshop will give you some) It comes in three thicknesses. The thin or middle one should work for you.

Clean all traces of old adhesive off both sides with solvent, and put one strip on each side of the vee, and it'll never come off.... (unless you take some dental floss to it).

 

Thanks Silver06... great advice!

 

Take it back and make them fix it.

 

Plus there are two little plastic safety clips on it too.

 

Thanks everyone... got it on pretty tight now.
