That harbor freight blaster should do fine. Play sand might work but it might not be dry enough and its probably inconsistent in grain size. Silica sand is effective and cheap! I get it for $5 for 100lbs. What ever you use keep it dry or you will be very frustrated! Oh and get a good hood and respirator..

After years of study, with the smaller siphon blasters...

Available at garden supply stores is kiln dried#60 grit sand ...

#30 will work but the#60 is finer will cut better..


Don't breath the dust!... ... Wear eye protection

I bought the hf 10 lb pressure feed blaster when it was on sale awhile back. Let me know how it works, I haven't gotten the chance to use it yet. Hopefully it is at least a little faster then the siphon feed I was using. I have used regular silica sand before, and it works fine, BUT like others said, it is very bad for you if it gets in your lungs. Do a search for silicosis. And getting moisture from the compressor will cause it to clog the blaster. I know the other guys already covered that. Also the media tends to go everywhere, so move other things from the area and be prepared to spend a lot of time blowing it all out of nooks and crannys of the frame.

I don't know about that pressure feed blaster from the Chinese Red Army store.

I bought one as well, used it once, it SUCKED. I went back to my old gravity feed and "Speed blaster" without a problem. I was using the proper sand, had plenty of air (or so I thought) and it just wouldn't take the makeup off a sick whore.

Oh, and Chris, please note that Milo was going to TOTALLY tear that chassis apart and REPLACE all bearings, bushings, master cylinder, wheel cylinders, etc, etc. Sand blasting something together like that is a BIG NO-NO, these componants will be RUINED. The sand gets everywhere and over time will TEAR THESE COMPONANTS UP big time.

Barry, people from other parts of the country don't have a clue as to the magnitude of the idiocy in California law rooms. You are aware I see. Yes, in the sunny (well not lately) San Francisco bay area where Milo and I live it is ILLEGAL to sand blast and not contain the sand. There is a different governmental agency for just about anything you could do, the one that cares about this is the "Bay Area Clean Water Urban Run Off department." NO, I am not making this crap up!

That sand contains rust and paint, if it washes down into the storm drain it will get to the bay and hurt the fishies. This dept. also will stop you from washing your car in the driveway if it wants to (though they haven't gone as far as to actually in-force that). They DO regulate how cars are washed in car washes and in businesses like the shop where I work. The water has to go into a containment system which filters the water before it goes into the drain.

You cannot legally sweep up bondo dust and throw it in the garbage, it has to be contained in a plastic bag (no one in-forces this one either, but I was warned at my shop to do so).

Yes, and not only that, English is a second language. And people wonder why we are leaving this state by the bus load.

Wow, glad I live where things are still somewhat normal... I can at least wash my rides pee outside in the yard without being seen if I want too.
Reckon pouring my used motor oil around my "Deck" is a NO NO or letting grass clippings fall into my creek.. lol

Only in America boys... next we will go to war, blow up a country and then help rebuild it.... Oh wait a minute we already do that, but dont worry about those hit with the Hurricanes... they will be ok..


Sorry for the thread HiJack...

alot less nozzle "clogs" if you sift the playsand thru a piece of aluminum window screen over the hopper as you fill it....every bag will have more or less "rocks".....5 good bags....then 2 bad....then 1 good

your small tip diameter can make it very aggrevating with no sifting

Brian,
I knew they were nuts but that is about crazy.

Every six months I get a call from a county authority (same one) there and the call is the same every time! Just different callers.

Will you verify the VOC of this product?
Yes what is on the can is right.

No, break it down by solvent and send us or have an indep. lab break down?
No, what is on the can is true.

You have to do this or we can ban you from the state!
NO, you can band me from your county if I'm illegal and if your concerned,
you break it down.

That would cost $500 to do that!
So, the fine is $25,000 if I'm illegal sounds like a money maker to me.

Than all is quite for another six months.

Oh yes, I had a few of those calls myself. The funny thing was, no one knew Martin Senour products so they would many times not even try to understand if it was a "pretreatment", "surfacer", "sealer" or what ever. It was a gas, basically, if a shop has well kept, detailed records of VOC use, they are just not going to spend a bunch of time on it. If the shop has a pile of papers and an "I don't give a damn, this is BS anyway" attitude, they are in for trouble. If it "looks" like the shop is doing everything right, they will get a pass, it is that simple.
