Feature(s)

Coarse and angular-shaped particles cut through paint, rust and mill scale. Produces very little dust during blasting and boasts faster blast-cleaning speed when compared to other slag abrasives. Typically it is composed of ferrosilicate (Fayalite, Fe2SiO4) material and oxides, formed when the molten slag is quenched in cold water.

 

Did some searching and reading today.  Interestingly, I don't see anyone selling copper slag in the US.  I see shopping suggestions of other abrasives in Google Shopping when I search for copper slag.  Coal slag is available.  Both have descriptions that typically refer to applications which are thick metal (truck frames, trailers, etc.)  I see Black Diamond is available in fine and medium.  It's pretty cheap.  I think I will get some and try it.  I have a bunch of suspension parts and other similar items that need to be done, so if this is too aggressive for body panels, I still should get use out of it for these other items.

I liked the Black Diamond for stripping paint, plus the texture on some things.  You can strain it and reuse it a couple of times.  50lbs for $10.

The car with most of the exterior stripping and metal work complete.  The hood got some more work after this pic which can be seen in pics I already shared.  The tail light panel and rear apron received a lot of hours because of the light tap that the car took at some point in its life.  Also, the front passenger side fender was damaged as you can see in the bring a trailer pic at the bottom of these:

    

    

    

    

    

Some rust through on the lower corner of passenger fender.  Also more metal work to be done on fender (middle pic)  Shrinking and stretching was necessary to get this area in good enough shape to require only a skim coat of bondo.

Wow... such a great condition car! Mine was nothing like that....

I used the copper slag on the underside and inside of the car but not on body panels. I used EZ strip wheels for that.

Good to know.  It seems copper slag and coal slag are pretty aggressive compared to play sand.  But much safer, I am sure.

Once the outside of the car was stripped to that point, I mounted it on a rotisserie:

That's a nice rotisserie!

I say just clearcoat it as is. Doesn’t get much better than that.

Now throw a briefcase full of cash and cocaine in the hatch and head for 88 mph!

Haha!! I'm not quite to that level.

How about a fanny pack with a handful of Canadian Tire gift cards and some ibuprofen topping out at 88 km/h?
