Ian, I crawled under The Road Toad with a litre of Tremclad gloss last week.I'm still stiff and most of the black spots have been scrubbed off my body. Figger the Trill lasted 35 years exposed to the ravages of the Canadian Tin Worm...and no major damage...my coat of paint
might get it through another ten at least!
On a related note, after viewing all the dire projections of Dexter axle
life, I asked Hitch Guy if I should be looking at replacing mine. I still have a full four inches clearance, no bottoming out, no sags. He said he'd never seen one fail or had to replace one
So we'll keep fingers crossed.
Now if I go back to polishing the wheel wells, I'll know I'm ready for an intervention
