Great product!
I followed the included instructions to the letter, and it applied perfectly to my new mailbox. The extra numbers for the door are very nice, too. My mailbox has shallow ridges on the sides, but the big decal applied great anyway.  I gave the entire mailbox a sprayed on clear coat afterward just for extra protection.  The dark brown numbers and lettering look really nice on the grey mailbox and match my house numbers.
