Sand blasting
I see on a lot of the projects here that people are sand blasting their cabs and beds.
How are you doing this without distorting the sheetmetal?
Sandblasting creates heat and heat distorts.
It has always been my understanding that sheetmetal needs to be cleaned with soda or walnut shell.
Someone please enlighten me.
I am close to taking my 66 LWB apart to start a frameoff restomod. I would like to get a soda blaster but Im not sure what it will cost to get a adequate setup going.

When I sandblasted my 1966 F-250, it was 40 degrees, outside, 1o to 20 MPH winds. I did everything underneath and inside the cab bed and fenders. Then on the outside just the seams, pockets, tailgate, what ever would be to difficult to do with sander (DA). Keep the blaster nozzle farther away when the metal is thinner.

I have sand blasted sheet metal parts for years, never warped anything. Never even got a part warm to the touch. It's all common sense....
Keep the air pressure down around 100 psi, use the finest grit sand, keep the nozzle at an angle and far enough away to still do the job.
And WEAR a RESPIRATOR! Silica dust is deadly!
It also takes a HUGE amount of air to blast......make sure your compressor is up to it.....

You need a lot of air volume, not really high pressure. Blasting will kill a small compressor.....

I've got a 150# pot that I've had for years (ALS or ALC, can't remember) that I use for tractor parts. They make a soda attachment for it that i would like to try. But the other guy's are right. These older trucks have fairly heavy sheetmetal (compared to todays cars), but care and patience is the key to sandblasting sheetmetal.
