This is how she turned out in the end...
I spent 4 years as a detailer just out of highschool for both Chevrolet and Porsche. I've got a lot of time behind a buffer and trying out different brands of chemicals.
My process is 3M Perfect-It line of products finished off with Jescar Powerlock and Collonite Insulator wax as the final step.
This particular truck took a LOT OF BUFFING to get the primer to shine, and HOLD the shine. This also meant that there is some bare steel now showing.
If I had a dollar for everyone that asks what kind of Clear Coat I used for that "Patina", I'd be a rich man... I was even called a liar for telling a guy that it was just buffed/waxed...
A coat of Jescar and Collonite keeps the flash-rust at bay on edges and thin spots.
I think that your Blazer would look AMAZING all shined up....
