Keith should be able to give excellent advice/insight on this. The tubs are all imported from the Philippines with a variety of fitment issues. Hopefully, Willys Overland can get it closer to "bolt-on". As built, it is not bolt-on. When media blasting and repairing an OEM tub, we used tinted bedliner on inside and underneath. So far so good. Not familiar with Bullet Liner product, I heard WO subcontracts that application out to local shop.
