Dyna-Glass filler

 Removed a lot of the trim today and began bagging and tagging in earnest for this project. Was pleased to find no rust hidden under any trim.

I also applied a first skim coat of Dyna-glass on the RR wing. This is how 3M describes this filler: "Dynatron™ Dyna-Glass Short Strand reinforced body filler creates waterproof repairs that are twice the strength of ordinary body fillers"

 
This can go directly on the sheet metal without fear of harboring rust since it won't absorb and hold water, unlike ordinary talc-based filler. It also strengthens the metal a little, which a good thing after doing so much hammering and sanding. 

The skim coat is evenly applied over most of the surface and in some known low areas a couple mm thick.

 

Most of it gets sanded back off, stopping when the high spots in the metal are revealed. It's nearly transparently thin at this point. One more thin skim coat will be applied and rough-blocked after which it will get sealed with epoxy primer. I'm happy with how this is turning out.
