So far: I see a lot of worry about this lining breaking apart and I am not sure why. I haven’t seen anything here that suggests that the lining is not weather capable, and it does not seem particularly absorbent. It’s not cardboard. It can be soaked and maintain full strength as far as I can tell on my car. The issues I see are: 1) Bolts must be present and tight enough to not loosen. I need to look up a torque spec on a torque chart, but mine were at 2ft-lbs which is not enough. If any come off damage can occur. 2) in winter, possibility of snow chunks from tires dumping on top of the cover weighing it down enough to rip it off. It is hard to tell without having the vehicle lifted, but to me it looks unlikely that this is a problem. 3) the rear bumper cover can fill with a lot of water (and freeze) when parked facing uphill. When level, there doesn’t seem to be an issue. The bumper cover also has two bottom bolts that must be present and tight. The middle one has no hole AFAIK. The bumper cover issue seems unrelated to the composite axle cover issue to me, though they have the common theme of loose bolts causing problems. The composite sheet doesn’t appear to accumulate water from what I have seen in all the prior videos and the other thread. Best thing you can do here, in my opinion, is to immediately check that all bolts and washers are present and tighten them to the torque spec.
