Proflex caulk and fender skirts

[myredracer]

There is a caulking seam along the top of our fender skirts which has pretty much failed for the full length on each side. Due to flexing while in transit I guess.

Question is, I assume fender skirts are typically HDPE plastic? Almost nothing will stick to HDPE so would it be a waste of time re-caulking it? I see that some TTs don't use caulking at this seam but I *think* it's needed on ours, at least for part of it where it transitions from the fiberglass sidewall to aluminum J-wrap. Maybe it's not needed though?

Proflex RV and the Geocel 2300 are the same product.

I did a bit of caulking where it opened up, but I reduced the shaking by installing homemade snubbers.
