I was looking at getting some Media for my blasting cabinet.
I was wondering if people a preference. There is talk on here about the use of Fine Garnet. I was wondering about Glass beads.
I am using some rubbish I got from super cheap but doesn't seem to be much chop.

Depends what you plan on using it on. I use the radum medium garnet to clean mill scale and paint etc off mainly mild steels.

The sandblaster down the road from me uses fine garnet (on much more powerful machines). He uses glass beads on stainless steels.

Remember, the abrasive will get smaller and smaller as it gets cycled through the system anyway so you will end up with it being a fine dust until it just won't cut anymore.

I really only what to use it on small body parts like hinges and a like. The stuff I have from super cheap has a real hard time stripping the paint.
Does any one know of some where a bit closer to box hill. I can get some media. I have done the usual search of the web. But it looks like maybe Dandenong or Tulla maybe it.

I have not seen the stuff from supercreep but I can tell you that painted surfaces do take a long time to strip depending on how thick the paint/undercoat is.

Unless you have one of those full on industrial blasters with a gun/nozzle that you have to hold with both hands (like a fire hose) then you have to realize that it takes some time to strip some parts.

For example, I tried to blast the bumper bar brackets that had minimal paint and a rough textured finish, well that took just a couple minutes each. But just as a test, I tried blasting a piece of an old bonnet I had lying around and that took what seemed like forever to cut through to the surface.

That is interesting. That is what I find. I think it is defiantly a limitation of the little blasters. It is good to hear others feedback. I am probably expecting to much from the unit.
I would like to give Garnet a go  :)
