Best bed liner for coating my fender flares?

Yes, Bed liner. My grill got it done at a off road place that has line x, but it was pricey. I want to do it myself, just worried about it bubbling. My flares are off, any opinions?

 

I used Duplicolor Bed Armor in an aerosol can for my sliders. Seems to work well. And you can spray more coats anytime to touch up trail damage.

 

This. The spray on is a bit cheaper than the roll on stuff and it's easier to hang on to for later touch ups.
Just take your time and clean/prep the flares and you'll be alright...

 

I had my fender flares and rocker panels Line-X'd and am very happy with the look and what seems to be the protection factor. I was told that to prevent fading they had something they could add (UV protectant) to keep it from fading. I think it looks nice - good luck with your truck!!
