Well, inspired by Dave's post I spent all day today taking 2 treads off the drivers side wing, cleaning polishing and refitting
Mine were really bumpy caused by the rust build up on the bolt heads
It was a b##### of a job ! Getting those nuts off corroded threads also gunked up through years of wax oil and bolt heads that just spun in the ali channel recess where I couldn't get any pliar grip
It left a lot of black gunk on the wing which cleaned off well and I gave the wing a good polish with Autoglyms resin polish then some wax
Also cleaned and polished the tread channel
Both back on I'm pleased to say looking nice and flat and using stainless bolts and nuts with nylon washers
Used copper grease and ACF50 to hopefully stop any moisture getting in the holes and prevent ali to steel reaction
Also used Armour All non silicone semi- Matt vinyl protectant on the treads after they were cleaned off and before I got them back in the channel - that was the easy bit
My hands are now sore but a nice sense of achievement even though I'm the only one who will notice the result
