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.

Rear wing panel beating

If I'd known it was so bad before doing the dogleg and the rear panels I'd have just gone for the full replacement wing. It aint pretty, but I think it will do. Got everything within a mm or two of where it belongs. This will mostly fill with just a skim coat. 

Rear wing bondo horror

 Moving over to the right rear, there was some bondo that needed stripping. I didn't know what I would find, but I figured if I kept digging deeper I'd eventually hit metal.

Here's why old filler can't be trusted: Loose patches with rust underneath. It all has to come off.

I used a heat gun to soften the filler and a wood chisel to scrape it away. Works for removing multiple layers of paint too.


Did I mention that the former body man was very fond of bondo? He was also not fond of straightening sheet metal.
