No glaze putty. Used a high build primer. Fills in most hair line scratches and gives a little build for final blocking. The whole car was done in Omni brand from Arnold's. Little less expensive but lays nice and you can't tell quality difference from the more expensive brands and prep work makes the paint . Another brand I've used is Nason. I've had good luck with it too.
All metal is similar to bondo, except rather than talc, they use fine aluminum dust. It's 2 or three times the price of plastic filler and you definitely don't want to apply any excess, it's next to impossible to sand.
Kind of threw me for a loop as I used to ride bikes with a guy that was the 'Lead Man' for a Rolls Royce dealer, very old school 50/60's Hot Rod chop and channel guy, very famous for his 50's flamed out chopped and channeled Merc. He had to have a Prism(?) on his dash so he could see when the stop light changed at intersections. He also had a chopped early 60's
