Thanks again for all the new suggestions. I really appreciate it as it has given me several options to try out and see what last longer.
On a separate note, after inspecting the exterior trims on my 2015 EX that need restoring, I just realised the rear wheel arc does not have any liners at all. The front does on at least 2/3's of it but the rear ones only have at the very bottom and not even much, while the rest are exposed metal. I found it to be an odd choice by honda.
