wet sandblasting? anybody try it

I had a fellow tell me about sandblasting with a high pressure washer and a sand blaster attachment.

Has anybody tried this method?

I like the idea of not having sand blowing all over the place and plus I can buy a pressure washer and do blasting when ever I need to.

I have a frame rims and underside of the body of the 52 to blast.

I would have to rent a 175 cfm compresser and the sandblasting pot.
This seem like an much easier way to blast.




thanks

Looks like it would only be good for large areas, and you'd have more water than sand in the mix so it seems it might take longer. Also, I guess it wouldn't be a huge deal but something about spraying water over everything I just turned to bare metal makes me leary.

However maybe the water would also keep the panels cool while being blasted and really cut down on panel warping?

 

I'm not big on the H2O over bare steel. Although I guess it would make material removal a little bit slower and heat really wouldnt be an issue.
But then again, the guys who do my 'blasting have NEVER and I mean NEVER damaged one of my panels. Good guys who take an interest.

They are in Spokane by the way

 

i did a 40 pu with a wet blaster about ten years ago, took forever to stop the rust it created.

blasted, etched, etched ,etched , etched 4 times, never will i do that again.

I've done it in an industrial set up, inside a booth. It's more like dirty water than abraisive. And it produced a very fine frosted effect. But it was slow and I can't imagine trying it at home. As for post rust issues this was done on aluminum, although steel etc was done from time to time, but promply dried etc.

 

I did a whole surface rusted pitted roof, worked well but after it dried I had to hit it with a sander as it started rusting immediatly. Alot less mess, I even did the wheels while still on the car with tires.

 

You may get the stuff clean but it will rust INSTANTLY.

 

When American Race Trucks were still in production, they used wet-blasting to clean the GM Metric donor ch***is before fabricating the tubing cage ***y.

Rust....Yes they will turn a yellow tinge within hours of drying, but use a good moisture displacing lube on them immediately after blasting (When they r still wet).

Slow....Dont use an electric driven washer. Use a good gasoline driven washer of 2,000-3,000psi output and it is as fast as most air driven units.

Let the sand dry out and it sweeps up for screening and reuse too.

They produced in excess of 140 units in one year. Wet blasting seemed to work well for them.
