Rusty floors: A Home Remedy
Posted by Glen in Montreal [Email] (more from Glen in Montreal) on Tue, 24 May 2016 20:49:04
I owned my 1988 900TC for almost seven years before I thought about lifting the carpet to admire my floor. If you had asked me I would have said there was no rust. In reality the lower rocker interior wall had a gash about six inches long and there was very little good metal connecting the rocker to the floor pan..
My preference would have been to have it welded but the topography of the damaged area was so irregular I couldn't imagine any solution that didn't start with a big gaping rectangular cut out with no guarantee I could either bend the new metal to my satisfaction or find a willing welder.
So I fixed it with epoxy. I did the repair in two stages: the first, after grinding and prepping, was to seal the interior with J B Weld and fibreglass matte: the second was to restore the structural connection between the rocker and the floor with a steel angle immersed in a pool of J B Weld.
The angle is 16 ga, I couldn't find anyone with a brake so I knocked one together with wood, a couple of door hinges and some aluminum angle.
I wasn't confident I could screw my angle to the floor given its condition so I screwed through the floor into a plate underneath. I had thought of actually creating a sandwich with the epoxy-reinforced remains of the floor between the two plates, screwed and epoxied, but a little experience with the J B Weld increased my confidence in it and now I intend to remove all the screws and put my faith in its adhesive properties.
(I'll keep you posted!)
