I agree. I apply my filler to bare metal and once I’ve blocked it all out I spray 2K epoxy over my body work. With the 72 hour window I then spray my high build primer to cover any scratches or pin holes to avoid using glazing putty at all. I block the entire panel after it is buried in high build then seal that just prior to paint. It is a lot of steps but I’ve had great results.
