Need some help from a rust guru!

^^ All just depends on how much time and $$ a person has, what his personal expectations are. I have seen many people make a car too perfect to ever drive and enjoy!!
I see some shops using the"Dustless Blasters" now, I guess I is a combo of water and sand??

Had it done . Never again, Try and get that packed wet sand out of the rails and rockers, Or the roof and quarters. Never again.

It takes three days of turning a dry blast job on a rotisserie and sand is still coming out. Wet blast is there forever and holds the water so rust is inevitable

Chemical dipping the is worse if the body isn't electroplated instantly. it will seep out of the seams for years

I found over the years the way we do them is the most economical and easiest. We have bodies here that are completely stripped that are ready for a resto. Some don't need that. This bronze Duster is a driver and will be sold cheap. Blasting the surface rust off the bottoms of the rockers was the easiest. Cheaper then sand paper. If you notice we have a truck tarp under the car. we keep reusing the crushed glass. Less heat

Crushed glass flows out of the rockers and frames much easier also. Sand doesn't flow out and holds moisture. We have a couple blast cabinets. The cabinet with glass the vibrator keeps the table clear. On the soda or sand cabinet you have to wipe it off the table with your hand. The soda needs an agitator in the bottom so the cone don't pack from vibration. turns hard like clay.
