Anybody here use Shark Hide

[old2soon]

metal protectant?? A P G R guy on the last mission mentioned it in passing. AND I read a few positive comments but wondering if some brothers and sisters here have given this stuff a whirl?? Tad bit spendy so looking for any pluses or minus's!  Went on a P G R mission when the roads were wet with salt residue.  Did NOT feel like dropping the rear wheel so even after polishing again it looks a bit sketchy.  As always thanks for all and any help in advance.  RIDE SAFE.
