dustless blasting

anyone seen or heard of this form of blasting? Saw an ad for it in bsb magazine and looked it up. Looks like just a mixture of water and crushed glass.

They recommend holdtight 102 for cleaning of the metal after blasting. They claim there is no residue left. Looks like a great alternative for soda...considering there is no acetic film to neutralize, leaves an anchor pattern, and considerably less mess.

They claim it is approved by PPG, SW, and Valspar and lists tests from them. (both dustless blasting and holdtight)

Seems interesting by alway weary of these new "systems." Only downfall I can see from it, is that it might not remove the heaviest of rust and you are submerging the baremetal essentially in water. That makes a lot of gus cringe...but really is not an issue if it is blown dry.

Anyone have any info or experience with this? Going to ask our media supplier about it also..
 
That blasting unit cost $4000.00 (without air compressor)
Probably not prohibitive for a shop like yours,though.
 
When they did the math at the end they forgot to include the cost of renting/buying a 185 cfm compressor!
 
They did not include the amortized cost of the blast unit either. I think the assumption is that you will invest in both pieces of equipment and use the profits to pay for your investment.
 
ha that media they dumped in there was from new age. same company i get it from here. i didn't see pricing but if it is $4000 then thats about average across the board for a good blast pot. it also looked like they painted that car with like one thin coat of duplicator or something like that. don't think for a minute that it will blast your average car like that.
 
I realize the level of marketing they have going on there..LOL. They do have one video fo them blasting a ship that is supposedly marine epoxy. Not sure I buy that also. We already have the compressor covered. We currently are using crushed glass anyway...it isn't the new age stuff tough.

It may just be one of those too good to be true deals. I wonder how that glass in the caddy looks after this process. No where do they mention the hardness of the media with the water.
 
I noticed the 150psi requirement.
Also there is a lot of conflicting information on the pages of tests for the Hold tite 102 metal treatment they recommend.


Barry, what is your opinion on the use of Hold Tite 102 before SPI epoxy?
 
Hi all, I'm the video producer / internet guy at MMLJ, the company who manufactures the Dustless Blaster. The red Cadillac video is pretty unbelievable due to the paint being new and there not being a clear coat, etc. I did just finish making a new video with a car full of old paint, rust and Bondo, which will give you a more realistic expectation. http://www.youtube.com/watch?v=bCehkkTTeMk

As the video guy I'm not really the expert on the process, but if you have any questions feel free to call the number on our website and someone will be happy to give you any info you seek. Didn't come to argue or sell or anything, just wanted to share the newer video.
 
so who cleans up the god awful mess left behind ??

for those interested the moh ( measure of hardness ) of the products is below

soda - 2.5 - no metal removed - recycles - 0
plastic 3.0 - no metal removed - recycles - 8 - 10
crushed glass 5.5 - med metal removed - recycles - 1 - 0 with water

anything that leaves an anchor pattern can warp sheet metal . it is not heat but rather stretching the outside of the metal that causes the warp.
 
For $1000, at least they could wash it into the gutter, but there is a question of whether the sludge is considered hazardous waste.

I think keeping the dust down is a great thing, but the compatibility of the Hold-Tite with SPI products remains an open question.
 
looks appealing compared to my blast booth in summer but damn i would not want to be doing it in jan . i do have cool air coming into my hood so i aint too bad.

x2.

Totally forgot about this thread..lol. One thing to mention...how bout the water bill for that hr of blasting?

I'll say this too... $1,000 to blast the outside of the car only......is a rip off to the customer. Or maybe our blasting rates are too cheap...LOL.
 
It's too much.

Yeah, shine, in January we'd be making icicles and slippery slopes with that rig, unless it was piped for hot water!
 
So I thought I'd give this a little bump and see if there is any current experience on the dustless blaster system. Also I see Barry hasn't responded if the holdtite 102 would be Ok under SPI products.
 
I'd be curious on the holdtite also. I read some stuff on it a few years ago but haven't heard anything since. I like the idea of the blaster also. Other than the heated booth in the winter.
 
so much for the dont wash them after blasting ................ :)



and i'll admit i do run the air high in my hood in summer . little trickle of cool water down your back feels pretty good. but it will wake you up when it hits the crack of your butt !!!
 
Thats what looks pretty good to me. I blast and then try to airgun/soap/water/powerwash whenever possible. This looks like it would save some steps I don't enjoy.
 
not sure i would want the mess. seems you would end up with a lot residue and glass in a muddy mess. when my media gets old i use it to fill a raven on my place . i dont know where i could do it wet plus i would never use good well water to blast with.
 
The non recycling of the media would be more expensive and your right about the mud. Is well water scarce in Texas?

I need to know this about Texas as when they seperate from the Union then I'd have to move down there. :)
 
someday water will be more expensive than oil . we have a good well. but i hate to waste well water . hell i go outside and water a tree :)
