Bed liner in wheel wells?

I'm considering this as rock and gravel protection. The rest of the underbody, engine house, frame, and axles I'm using TSC black implement paint. I would be going w/ Duplicolor bed liner over sand blasted panels b/c it appears to be smoother than others. Any issues like horribly hard to clean dirt off? Does it fade quickly? How does it hold up to tire scrapes?:v6:

 

I used rattlecan black undercoating on a truck I sold. Worked good for me and it was cheap. Held up pretty good and I would just touch up every now and then.

 

Used undercoating worked well

 

What kind of undercoating are you guys talking about? Most I've seen is pretty weak stuff. The TSC implement paint is generally tougher than the ones I've seen, just don't really want the high gloss there.:v6:

 

I used the Durabak (the rougher stuff with the rubber bits in it) with great results. Seems to stick aggressively, haven't had any peel off yet. Even had a bit of wheel scrub and it hung in there. I used the black on the underside and red on the inside of the tub. Cleaning is a breeze with a hose, but does tend to "dull" out a bit with some dust and such.

 

i used the cheap rubber undercoating in the rattle can. had some of it come off, but most is still in place 2 years later.
