Pressure washer sand blasting

[Coolerman]

I have a Harbor Freight pot blaster and have done a couple of entire vehicle frames and bodies with it. One HUGE advantage a pot blaster has is this: If you spread a large tarp and put your project in the middle of it, you can grab each corner of the tarp after you have emptied the pot and all the sand can be quickly put into a pile to be sifted and reused several times before it's worn out. The worn out sand goes into my Harbor Freight bench top blaster to be used for more delicate things like aluminum parts. I also use the playground sand from Lowes and sift it using screen door screen to remove the small pebbles. The pebbles go into the agg pile for use in concrete projects.

I also have a Harbor Freight Soda Blaster that is used to clean electrical harness plastic connectors of grease and grime and their brass terminals of corrosion. Low pressure for this operation (60 PSI vs. 135 psi for the pot)

Harbor Freight sells 50 lb bags of soda which last forever in my case. I have also used the soda to remove paint from various fragile things like dash knobs and such.

The blue gizmo is the Harbor Freight Soda Blaster...

there is some good info here, I am researching b/c i have two stock trailer 20 & 24 ft i need to blast and paint and I am debating on sending it out to a "blaster" or getting a pressure washer and doing it myself....

For restoration and any time full paint and rust removal is the goal, it's hard to beat a good sand blaster and the right media...A good compressor is also paramount to success...

I use a 3500 PSI washer with General pump sandblast kit and Black Diamond media. Solved the feed problem with a cone bottom plastic tank that agricultural sprayers use for mixing chemicals. I just drilled a hole in the top that is a snug fit for the siphon tube. Keeps the media dry an feeding.

Any pictures of your setup?

You can add rust inhibitor solution called holdtight that will prevent the flash rust from happening after sandblasting
