I once decided to take the rubber inserts out of the previous Mog, on the underside of the running boards all looked excellent due to years of regular waxoil, but after the inner ends of the tiny bolts were exposed wow ! The heads were just a mush of corrosion & looked like just mild steel
I replaced all with 316 stainless & 'Dr Dave' W used my photos for his Miscellany article
The ally channel just acts like a water reservoir & for me I would not by choice, have them again
