Warped Plate

The cut on my hand has recovered 90% plus the weather was very fine. Really a nice evening to wash the Accord (Hasn't been washed for 12 days!). Within an hour, everything was done. However, found out that the new rear number plate has warped! It means more time needed to take it out, to remove the double-sided tape residue, and to replace the old one. I'm going to contact the number plate shop to ask for a replacement. Such a poor quality plastic.
