Chrome Delete BumperShellz

For those that have this product... does the plastic noticeably shrink/expand duing the summer/winter and is there any problems with it trapping moisture creating rust issues. Would you recommend? https://chromestoppers.com/collections/all/products/2005-2015-toyota-tacoma-rear-bumpershellz™-chrome-delete-truck-bumper-caps?variant=37643251187883

 

I have had my Bumpershellz for over a year, thru winter and summer. There is no shrinkage or expanding. I haven’t had any issues with rust or moisture being trapped either. I would 100% recommend, they are tough and durable. They also look great. They are high quality.
