Just found this new system from dustlessblasting.com. Uses ground glass and water to remove paint/bondo/and rust very easily and won't warp thin metal. Only problem is you need an industrial air compressor, but it will strip a whole car in less than an hour! A rust inhibitor in the water is good for 2/3 days protection until priming and it is also environmentally friendly with easy cleanup. ( no, not affiliated with this tech in any way, but seeing 356's and vw's painfully stripped manually, hurts). Check it out.

Some of the chemical plants around here have been water blasting for quite some time. I'm not sure if they mix in glass or not.
The plants like it because of the clean-up factor and the on-site/close quarters capability.
Dry ice works well in the plants too.

That video looks pretty neat.
God Gosh that Chevy is rough!

That dustless blaster is out of reach for almost all DIYers...the machine itself costs about $3,000 for the smallest unit.

Maybe if enough people comtact them about a home unit, they could put one together we can afford with a home compressor, say 30 gallon?

Sorry, but a 30 gallon compressor is not enough to operate a blasting system like this no matter how small it is. That 30 gallon will be continuously working and will break in no time. At minimum, you should have a 80 gallon system with about 20cfm to get a blasting system going from my experience. If they were to make it small enough for a 30 gallon, then the effective blasting area will be a pin point and take forever just to blast a fender or something.

Yes, HF sells a similar setup too. It works fine on rims, bumpers, chassis, etc. I'd be cautious using on sheet unless a spot or two as it will warp. Your comp air and media must be super dry too.

Unless you have a huge diesel powered compressor running it you won't warp anything, I blasted my whole T34 with one of those HF blasting tanks and a 25cfm compressor.
Works awesome.

I've been looking at the big system blasters like the trailer mounted Dustless Blasting one. I had a try of one from another manufacturer here in Adelaide at a shipyard. Worked well on Heavy steel, concrete, a 44 gallon drum and a painted timber pallet. All results were excellent in my opinion.

Have any of You ever had a car done this way? What were the results?
Warping? Surface? Debris in cracks? Painting after blasting?

The Youtube results seem good enough but would you pay to have your car done with one?

Hey guys, I just bought a dustless blaster from Northern Tool:

http://www.northerntool.com/shop/tools/NTESearch?s...2C+8.0+GPM

It's similar to what metalchomper posted above.

It connects to your pressure washer. I put a ball valve in the line to regulate the amount of media. Works like a charm!

I found a YouTube video of it in action:

https://www.youtube.com/watch?v=f87jqnbELfY

I did some research before buying a small media blaster that connects to the air compressor from Hobo Freight. Apparently, it can clog easily if you don't have a good drier/ water trap in your line.

That's my experience. If you want, I can post a pic of my set up.

I saw a Youtube video with Chris Vallone. He had a bug done with Dustless Blasting. It costs about $1000. They used a rust inhibitor called HoldTight 102 to prevent flash rusting for up to 72 hours.

The Chris Vallone one is one of the many I saw when first doing research.
A few weeks ago I got to use a Quill Falcon trailer based one at a ship yard in Adelaide. Was really impressed with how it worked on the different things I blasted.
Concrete - held back and just cleaned the surface then got closer to create exposed aggregate, and even in closer to break away right to the reinforcing.
Wood- took paint off of a pallet without damaging the wood beneath, a quick sand and it would have been ready for paint.
Heavily rusted Steel beam- cleaned up beautifully, taking away rust and debrise, left the metal clean and ready for repair or repaint.
Light Steal 44 drum - Took paint off without denting the surface profile. The surface has a very light pitting that would be easily cleaned up with a fine sandpaper or easily covered with good quality primer/surfacer.
All this was with Staurolite media. The owner said that ground glass would be gentler on the surfaces.
My opinion is that the result was excellent. Now I have to find the $ to by one.
This was a big $ industrial unit, so I'm talking a business purchase not a home yard purchase.
Next step for me will be taking a panel down to the bloke and seeing how that goes.

Make sure you completely blow out all glass before painting or it will be all in your paint as well. Car on rotisserie is best . My guy used walnut and if your car is completely appart which is best it will take much longer than an hour to complete.

Sweet looking ride Mate. Was the walnut shell blasting wet or dry?
As with every type of paint removal, cleaning out the debris both chemical and physical is probably he most important thing. Kurt mentions it in the Funky Truck thread on here as do so many others. I'd say it is the most important first step on any build when preparing for paint.
