I love this stuff on tires, it's easy to use and lasts a good bit. Just got done with a wash and applying to tires. While doing it I started thinking if it's ok to use on other parts of the truck. I put a good coat of it on the front wheel well liners, we'll see how that stands up. I'd like to hear what others think before trying it on the bedrails, bumper pad, lower valance, etc. My biggest worry is running, the truck sits outside and it is covered in dew every morning.

 

I wouldn't slather it elsewhere but, the wells are certainly an option...

Here's why... the stuff isn't exactly dirt cheap... The multiples of 'shine' products that I've bought over the years that I don't exactly 'like' go to die in my wheel wells as it's hard to mess up that area from a 'blacked out' standpoint.

Otherwise, you should be A-O-K... I'd stick to el-cheapo for the wells... either way though, you're good.
