One of the rear splash guards on my 2011 G37S coupe has started to come off from the bumper on the very top corner and I am afraid is going to get worse as water and debris gets in this gap. Any ideas on how to fix it besides taking the entire piece off and using new double sided tape? What is a good source for the double sided tape? Thanks for any suggestions.

 

I would go crazy glue or gorilla glue. Tape will just come off again IMO

 

Get the heavy duty RED souble stick tape......Home Depot sells it but be sure you have it positioned correctly because you will have a difficult time removing it. The problem with crazy glue or gorilla glue is that both the splash guard and panel are flexible thus creating the possibility of the bond separating over time from flex. Just my .02 worth. Good luck

 

You can always just use 3M double sided tape
