I can't remember if this has been discussed before (and I'm too lazy to check right now), but has anyone ever thought of Plastidipping the cladding? https://www.dipyourcar.com/home.php?...FcY7MgodhFYARA
Might have the same adhesion issues as the Line-X, but the Plastidip looks fairly inexpensive (if you get it in a rattle can) so you could just re-coat any pieces that may get scratched. You could also change colors on a whim.

I've had an idea for a paint job on the stock 18's for a while so I may try it out in Plastidip first since it seems so easy to apply and peal off if you don't like it.
