Good to know on the two row crank pulley. Thanks for the confirm.
There was a lot of pitting all over the body and I was not happy with the film of undercoat left after several cleanings with nasty chemicals. So I decided it would be a good idea to abrasive blast the car. The question was what method. After lots of research and conflicting info I decided on "dustless" blasting. Basically its glass bead blasting mixed with an anti rust and salt removing solution. The liquid solution is also claimed to cool the metal as the glass beads abrade.
I hired a gent with a pressurized hopper and tow behind compressor.
Work begins.
This is the hatch from my parts car. Filler was clearly visible pre-blasting, but rust was minimal.
Material removal was very effective.
It was hot that day, so his hazmat suit didn't lat long.
Freshly clean
The plan was to seal the bare metal with epoxy primer after drying the metal. The first challenge was getting all the clumped wet glass out of the crevices. This was unanticipated and a major drag. After the glass beads break they effectively become sand, wet sand. Blasting air allowed me to get them clean enough for paint.
This worked for the hatch and doors.
When it came to the body though there was an additional problem, flash rust
Pretty upsetting. It was getting late in the day and the weather report said rain that night. I got the car inside. There are a lot more nooks in the shell so hours were spent drying, brushing, blowing and vacuuming glass sand out of the car. The next day I got the car outside and treated the shell with a metal prep phosphoric acid wash. This dissolved the surface rust. The paint shop assured me the epoxy recommended this metal prep for maximum adhesion. :roll eyes:
