the 3M tape is not very strong. Water and other moisture will get in. I had a problem with this on both the letters and the stainless grill. Use some clear latex caulk to seal the letters (works great). I removed the stainless grill and it is sitting in my garage. I will sell it too you for cheap if interested. You are better off at getting some strong adhesive from Ace hardware and installing the grill , rather than the 3M tape.
