Description

Join Dennis Gage and Benny LeCompte of MMLJ Dustless Blasting as they examine the history of media blasting and the processes that have been created to remove rust while avoiding warped metal. They’ll discuss the advantages and disadvantages of soda blasting, as well as the current best practices to achieve a “perfect surface.” They’ll also examine new blasting materials like recycled bottle glass and how to use them properly.

    I had this done on my Mack Truck. It's more environmentally friendly, and no "sand dust", but it still make a plume of vapor that contains the paint and water and...etc. The plume may drift 50 ft. And when the process is completed and dry, the glass and debris still hide in every nook and cranny (like sandblasting). It's better than sandblasting, but it's still a mess.

    I would be interested in this equipment for my auto body class at Lookout Valley Middle high school.

    We have been using Soda blasting since 1980”s in Ontario Canada on Electrical Transformers made in Canada.

    How long before you have to paint?

Well in the garage with me today I got Benny Lecompte from MMLJ. Benny how are you doing, man? Nice to meeting you, Dennis. Now MMLJ is like you guys have been in media blasting since almost the beginning, like back to the '40s, right? Absolutely, yes we have been but we're evolving company. We do a lot of research and development. Well, and you guys really after media blasting, sand blasting and the like, one of the problems was generated heat. You get warped panels if you're doing car restoration and things like that. So the next stage of the evolution was soda blasting and you guys kinda of created that, didn't you? That's right, we brought it to the market because there was a big need with major paint recall. Manufacturers were inundated with, tons and tons of cars to do and no good way to do it. Hand sanding.. Chemical stripping. You don't wanna do that. No. So you guys created soda blasting and one of the great things about soda blasting was it didn't generate the heat. It didn't generate heat or warp metal. And obviously that's what everybody was looking for. Well and it is great. I mean it's a great method but there are issues with it too. There are. Primarily with paint companies, we're an evolving industry and paint companies had to evolve too. EPA was pressuring with VOCs and other things but the paints became more sophisticated. Sorta like cars go a hundred thousand miles, paint jobs last a hundred thousand miles. Well now that's because of the acid primers. That's right. They give you a good tight bonding on the paint and this is a problem with soda blasting. So you got an acid primer, you got soda which is a base. You get an acid base reaction and things don't stick. They don't stick and as a result of that, there's no paint manufacturer that will warrant a known soda blasted car. So you had to come up with something else. Absolutely. Is that, what I'm looking at here? Yep, that's it. It's recycled bottle glass. And I'll bet you, a few of your viewers have contributed to that product. You mean like beer bottles, wine bottles. Beer bottles.. Well, I'm sure they have. Exactly. So this is like sand but it's not. It's softer than sand. It's softer than sand but in our process, the way that we put this together, most people when they think of sand blasting if I took what I.. Yeah. And I blew on it , it would go everywhere. Right. But when we put it in the machine, we put it in with water, we put the rust inhibitor in there and of course the recycled bottle glass. Now we have a tight compacted material, and when we throw it, it'd hit you with a thump. But it wouldn't go anywhere. That's right. So let's talk about the, you know. This is your Dustless blast director. I unpacked this baby, that thing is heavy! That is one industrial strength piece of equipment. Well, they're US made and they're Texas tough. Oh, hoo! So it is, I mean everything you see there the container itself, the almost these fire hose size hoses. But if I'm gonna load that thing up, I'm gonna open it up first, I'm gonna dump in the water like you said. That's followed by kind of a magic elixir. What is that? Well, actually the HoldTight 102 it eliminates chlorides. So what we're doing in our blasting process is not only are we, blasting the metal to a white metal finish. And by the way, you're getting rid of the rust at the same time, which soda would never do. But we're also cleaning the metal. So it's paint ready. So after that, then I come in with my recycled glass here and I see you hook that thing up to a pretty heavy duty compressor too. You need, you must need lot of air flow? Well, not necessarily. But in the case of wanting to do a truck in under two hours like yours for instance, that's exactly what we'd do. So you can really do a vehicle in a couple hours? A couple of hours, yeah. We would just rent an air compressor for a 100 bucks, get the job done. Now for your regular brackets or anything else like that, it'll run just fine off of 7 1/2 horsepower compressor. And then and off you go. Well, and made here in the USA? Made here in the USA, absolutely. And Texas tough.
