pressurewasher sandblaster attachment

[BFR]

since I have a lot of nasty paint/ rust removal in my future and I don't have an aircompressor capable of pushing a serious sandblaster I thought I would give this a try

on the battery box from my deuce
before...

after (actually just had a few minutes of daylight so just started)

I had to use wet sand, so I had to stir the sand with the pickup for it to work. (I'll get some dry sand tomorrow & see if I can just leave the pickup in the bucket)

BTW: You can still see the occasional spark even with water hitting the metak at high pressure

WOW it works I should look at one of those.

A buddy of mine used one and it worked quite well. I forget what he used on the bare metal afterwards to keep it from flash rusting.

I have heard that I can use brake cleaner for the rust issue.

Those pressure washer sandblaster setups work fairly well. They are definately less dusty than straight sand blasting!
Get some Ospho, or metal prep. Look for a phosphoric acid based solution. The Phosphoric acid will convert the surface to iron phosphate, which is quite rust resistant. After everything is dry, you can spray on a good coat of red oxide primer, I use Sherwin Williams brand. That should hold things until you get a top coat on the truck.

Hows that work? I'd get one if someone can tell me how it works....

 

[Recovry4x4]

Here's a stupid question, what kind of store sells Ospho? I need some myself.

I've seen it at Ace hardware. If you can't find it there try a marine supply house.

In the old days (early 70's) we would use aluminum storm door cleaner on bare metal right after it was stripped. Basically its just a acid based solution as mentioned. It worked well in the high humidity area I lived in (Chicago)

mcinfantry,

Looks like some great stuff! Where do you buy it, and how much does it cost?

I use a siphon feed blaster with Dupont Star blast. It's very fine and almost powdery and feeds very well in a siphon blaster. There's also next to zero silica in the star-blast media which helps keep you from getting silicosis. After blasting, I blow it off with a bit more air, then shoot it with a primer sealer out of a rattle can.

Here is what I ended up with after 1 hour & 200lbs of sand.

Seems like that's a lot of sand for that much box.

 

[da_sgt]

I'd have to agree, seems like alot of sand.
I go through about 90#'s a hour in my presurized blaster, and I could do a couple tanks like that on one tank

 

[BFR]

definately a lot of sand, but I can do it with the tools I have & sand is cheap.
BTW:
I used a fine grain sand today next run I'll try "play sand"

 

[da_sgt]

Wish I could say sand was "cheap" I'm paying $9.00 per 90lb bag of 70 grit, same price for the 30 grit I try to recycle my sand when I can so that helps a little

 

[SixBuy]

The pickleX looks interesting but gets pricey in a hurry! The phosphoric acid based metal conditioners are much cheaper and work well if you follow directions and rinse. Also you can buy them at most auto paint supply houses too. About $7.50/pint which dilutes 5 to 1 with water.

just out of curiosity... do you guys think it is worth it to go all the way to bright metal?

I'm currently planning on using this to remove scale and peeling paint, then prime & repaint. Any thoughts?
