Wanting to put in a drop in bed liner but want to prevent it from rubbing paint underneath it. Is there a protection liner I can put in between liner and paint?

 

You can use a plastic or rubber mat between the bed liner and the truck bed. This will help protect the paint from rubbing. Look for a product made for this purpose, like a bed mat or a thin rubber sheet. Just make sure it fits well in your truck bed. This will keep your paint safe and make it easier to remove the bed liner later if you need to.
