Factory Bodywork Prep Questions (1 Viewer)

[LDRF]

I have factory front fenders and rocker panels for my 92 HZJ73. They come painted in what I understand is black e-primer (electrically adhered primer). What's the preparation process to paint the fenders? Do I scuff them up with 320-grit sandpaper or Scotch-Brite pad, apply a coat of primer, lightly sand, then two coats of paint and a final clear coat?

For the rockers, I have to weld them in, so will need to sand to bare metal where I need to weld first. Do I use weld through primer, then weld them in? Then prep with body filler and sanding, then prime and paint as above?

Any tips, tricks, advice, et cetera are welcome.

I found very little burn-back of the e-primer, so I would keep the sanding to a minimum.

For a different car, I was told scuff with non-woven abrasive (medium, red or dark red) then apply primer.
I will use 2 part epoxy primer.

You should SEROIUSLY consider using a 2-part panel adhesive (glue) applied with the special dual "mixing" caulk gun.
I did this on my minitruck and there was no heat, splatter, no burn-through, no weld grinding, no seam sealer required.
I read recently that the SEM panel adhesive can be used with welding, i.e. a few spot welds to hold the panel in place while glue sets.
You do have to get both surfaces to bare metal and make them very very rough. I used a cheap Harbor Freight wood rasp to grate away at the steel and create a good "key" for the glue.

I really wish I had that glue when I was putting floors in my MGB. Seems like weeks of grinding and filling after making my own spot welds.

I forgot to say that I painted the panel before I glued it on. Easy. Still needs clear coat sanded.
Apologies for non Land Cruiser pics. Gray/black stuff is the glue.
