Crazy walnut shell blasting??

Is walnut shell blasting typically done with a regular snadblaster? I was hoping to use my Harbor Frieght 80lb unit.
What psi is recommended and how many pound of shells to blast a '67 coupe with 2 coats of paint? What grit?

any help would be greatly appriciated

Check the specifications of your blaster, it may give you the information you require. Wish I could be of more assistance.

1966 Coupe - work in progress ... I6 to V8
1962 Falcon - next in line

If I had to do that, I would try it on the bolt on parts first, like a deck lid or fenders etc..I have a 80lb blaster from HF, and it would take forever with that tiny nozzle.

I have heard of people using a pressure washer with sand mixed in the fluid somehow, that keeps the dust & panel warping heat out of the equation but adds water and flash rust.

I've never thought of that. I'm not a chemist but adding vinegar to that water/sand mixture might help minimize flash rusting. Just keep the pressure somewhat low. Some pressure washers have a hell of a lot of force directed in a small area. Basically a waterjet is a high pressure water stream with an abrasive, usually garnet but could be sand, and I'm pretty sure that's not what you're after here...

Very good question. Harbor Freight sells walnut shell media right next to their media blasters. But of course, at Harbor Freight, that doesn't mean anything and the staff likely have no idea.

Look at my recent thread on Dry-Ice Blasting.

It would seem to me that if you use walnut shells in a blasting cabinet you can afford to use them because you might be able to re-cycle for a while, but if you're talking about using them in the open one time on large stuff, it would be too costly.
