Dustless blasting for your next project
 

this promo video is meant for a business but the idea is great. fast way to remove paint. I think a smaller unit can be rented.
Dustless Blasting Strips a '63 Impala in Under 1 Hour! - YouTube

Pretty cool, the guy doesn't even look like he gets wet.

Water on bare metal does not seem like a great idea?

well if you use a stripper, you have to neutralize it with water

Nice. I use glass bead in all my sandblasters I'd love to buy it for $10.00 for 50lbs I pay $20.00 for 25 lbs at a local body supply place.

I just paid $25 for 50lb crushed glass.

Use solvent. Or you can bast without water. I go to great lengths to keep water away from bare metal. You can actually trap water under a coating or paint and it won't become apparent for months or even years.

I think this would be good for loose parts. Forcing water into body will take days to dry. I had some parts cleaned with soda, Soda Blasting which worked well and didn't abraid the metal.

Water in the body shouldn't be a problem if the water is "practically evaporating"on contact, as the manufacturer claims. My issue is with the several ounces of paint that are now nicely distributed throughout the customer's yard...

This is very true. I had a very sweet BMW 2002 that this happened to. It was bizarre, the water made its way under the paint and came through - 3 years later?!?

That ground glass and pulverized paint isn't just magically being transported into the sixth dimension either. Once it dries there's the potential for a cloud of really nasty crap blowing around.

CO2 blasting is attractive

I was watching one of the shows on Speed Channel this past weekend. Either Chop Cut Rebuild or Two Guys Garage. They demonstrated a new wet media blasting system. One of the additives was a rust preventative. It seemed to work great, and with no rust issues. Unfortunately I can't recall it's name. If I see it again I'll Post the name.
I also found a few forums that say to stay away from Soda Blasting, many paint manufacturers don't approve it, http://www.crankshaftcoalition.com/wiki/Soda_blasting

Hi Ed, saw that too on My Classic Car (Ferrari episode) it was a company called MMLJ here is the link MMLJ - Leading the Industry through Innovation. There is an anti oxidation additive and they did discuss paint manufacturers not liking the soda blast media.

I paint sometimes and there is so much to go wrong before, during and after paint prep. Always new products/methods evolving who knows what our paint will look like down the road. Do your best and think ecologically drive the cars and let the chips, dings, die offs, small lifted spots all attest to how much we like to drive our cars. Things happen with use and time anyway.

a good point in general but I am trying to figure out the danger...

the paint is all dried, so you essentially have a dust with varying particle sizes (no chemical hazards)

same with the glass -- do the glass particles have sharp edges?

I heard you can add Marine Clean to the water so that the surface is oil free and ready to paint.

The sand and paint residue can be cleaned up pretty easily with planning and prep ahead of time (Plastic tarps and settling basins?).

Water under paint may or may not be an issue. If I got a hold off one of these systems there would not be any paint left on my car for water to get under. Did you see how easy they blow through paint! :D

Does anyone have any experience with them? All I can find is marketing BS.

I bought a DB500 unit last month. It works as advertized folks. The rust inhibitor is holdtight 102, which is in the blast mix, and used in the afterblast rinse. it stops flashrusting for a couple of days.I'm operating out of my cousins body shop in Hammond,LA. This is a new venture for me so wish me luck. The co. is called Ecoblast and the web address is ecoblastla.com , it's a bare bones site right now but there is a short clip of us blasting a 69 firebird fender and some before and after pics of a 64 El Camino.
The body shop is Damichi motors, add a .com for their site. If any Gulf Coast pelicans have any projects that our services might help you move forward, please contact me. Having a new state of the art paint booth on site doesn't hurt either.:D
This being the 911 tech forum, i blasted my stratton ducktail last week(paint match was off and i wanted to see how the blaster did on fiberglass). i block sanded it this morning and it should be in primer by now.
Happy Holidays

No hazard to paint dust?

Did you eat a lot of paint as a child or something?? :D

Call me crazy, but isn't most of the rust problems hidden in seems, wheel wells, and panels? A simple repaint might work, but on this car, there is plenty of problems going on.:confused:

[QUOTE=gtc;7164662]No hazard to paint dust?

what I said was no chemical hazard

one assumes he will not be eating it

if he wears a mask not much will be respired

how inert is lead-free paint once dried?

I've wondered about this finish and rust removal stuff for a long time too. It seems that each method has problems unique to it. Glass and sand are really tough on lungs if inhaled. I could see the fine dust created by blasting sitting around and causing problems when run over with a mower or on a windy day.

Thankfully i haven't come across anyone foolish enough to not have their project disassembled for blasting when it arrives. Remember the video is for demo purposes.

"Water in the body shouldn't be a problem if the water is "practically evaporating"on contact, as the manufacturer claims. My issue is with the several ounces of paint that are now nicely distributed throughout the customer's yard... "

the pulverized paint is mixed with the wet media, which thanks to it being wet drops to the ground much faster than it would as "dust".The ground under the project is covered in plastic. when the blastings done its like wet sand. We cut the plastic into strips fold and roll up and haul away for disposal.There is alot less dust that grinding and sanding, but folks do that all day long. After blasting and rinsing we dry smaller parts with compressed air and larger pieces get the leafblower.

I wear a niosh respirator, facesheild and ear protection at a minimum.

The pic below is a 74 ranchero a guy brought in last week. He was not happy when blasting revealed how bad a shape it was in. thing had bondo on 60% of the vehicle.the passenger side sailpanel was an inch thick. pic is of left fender and only 1/2 in. thick.

I am getting a car blasted right now.. the guy said no way would he soda blast a car due to not being sure you could get it all out for a proper paint job. He is going to plastic bead/glass bead my car. The cars he had finished with glass beads looked liked they were ready for paint! Will post up some photos before and after photos when done.
