I removed the original swing open door because I simply detested it, as well as the steps. The main entrance will be via the door to the old lifet, which was sold.
I plan on framing the old door space up with 1.5x1.5x1/8" steel tube, covering the area over the steps with a 1/8" steel plate reinforced with angle steel to mount a passenger seat to.
As far as securing the 1.5x1.5 steel frame to the opening, I am using 3M Marine 5200 Adhesive and some steel screws. I am also considering spot welding the frame to the bus skin every foot or so. What do you all think?
Overkill, unnecessary, utter stupidity?
Also, I'll paint the steel with the Rustoleum Rusty Metal Primer before attaching. Anyone have an input if I should leave the side that will get the adhesive un-primed/bare metal? Will the primer screw up the adhesive's contact to the bus? Does that also include the bus paint? Should I sand it to metal where the adhesive goes?
Also planning on using this adhesive to seal all the former rail holes in the floor. Plan is to use those small metal disks for roofing with a little bit of that adhesive to secure them to the floor over each hole.
