Rhino liner w/o cleaning bed beforehand..

So I just got my bed rhino lined today, and it all looked good up until I realized they didn't remove the bed bolts. I thought, not a big deal, I don't ever plan on removing the 4 bolts by the door. But I had to remove the two bolts at the end of the bed, next to the window, as I have traction plates + gas can holder mount to re-attach there. But even that I didn't care much and could overlook it as I was able to still unscrew the bolt.

But what is bothering me is that after removing the bolt, I found dust underneath.. I'm not sure where the dust was from exactly, maybe from the washer of the bolt.. but now i'm starting to think that they didn't prep it right/clean it thoroughly before applying the lining...

Has anyone here experienced this before, should I just wait to see if the lining peels off/bubbles and claim warranty? Should I call the shop? Or maybe i'm just overthinking it and the dust was just debris under the washer that got stuck? Gah, it just irks me because it was so expensive and if they didn't do it the proper way then what was I paying almost $700 for?

 

It's just debris from under the washer as you mentioned. With the amount of work needed to apply a bed liner, a shop won't shortcut it to potentially have to strip and do it again.
