SAND BLAST FIRST

[Schonyenko2]

A couple of thoughts. One is that you pretty much only sand blast the bottom, and frame parts.

Second, is that if you can see that you are going to need to replace a major panel, ie: a qtr panel, there's not much use in having it blasted with anything as you're going to cut it off anyway. If it's a question about the extent of the damage, that can go either way, but if the floor pan looks like this GTO, or as you can see on the picture, the rt qtr looks like it either had damage at the base of the sail panel, or what I expect is a replacement qtr cut in low as was common at many body shops back in the day, you're spending money on blasting a piece that's probably going to be laying on the shop floor.Saving money on a resto is a good thing. I suggest you blast only what you're going to save. JMHO
