Hi Shelby,
No rust at all. Super clean.
This was an early HabitatJK so there was some leakage when driving at speed (with clam closed of course) in crazy heavy rains. However, I took off the rubber seals on the top and bottom of clam, and sealed/caulked them all and filled some gaps and that did the trick. I would expect that re-sealing should be done every several years.
Thanks!
K.
