Rated 5 out of 5 by from Works just fine I'm new to blasting. This media took the mill scale off of the steel but it took a long time. Maybe I should be using a more coarse grit?

Rated 5 out of 5 by from Sand-tastic Ground glass work great but there's a lot of sand left over on the ground so be prepared to set up an enclose (plastic) so to prevent all the sand from going every-where.

Rated 5 out of 5 by from Best seller ever This company is awesome. Great service and fast shipping. When someone calls Eastwood you get a live human( hard to find these days) and they take their job very serious. There is no messing around. Those people have the customer service idea nailed down. Great job Eastwood. I will refer you always.

Rated 5 out of 5 by from 40/70 Crushed Glass Media Works Very Well I started media blasting my 56 chevy the first of this year and did the entire car with using 10 bags. I filtered the media so I could run it through two times. And even though the potential is far less for removing rust when using it over. And the dust is much greater... It does still remove paint and does well on small parts. This media does well for surface rust. It removed all rusted areas for me on sheet metal. I'm about to buy more as I need to do the frame. This time I will not recycle as I found a distributor near by. I also used the media blaster Eastwood sales. Only had to change one tip. And replace the bottom hose with a new one. As these wear out when continuously blowing this crushed glass. I found the media for $16 dollars a 50 lb bag in Fort Worth where I live. So for $160 bucks, not a bad way to go. Cost to have the car media blasted would have been $1500 dollars. I need 4 more bags for the frame.

Rated 4 out of 5 by from Works well. I bought this product to safely blast aluminum engine and brake parts. The ground glass works great at removing old paint, dirt and slight rust. Not the product to use on heavy rust or removing old powder coat. Working speed is medium to slow, but is safe, doesn't etch soft aluminum and left the parts looking almost too good to powder coat.

What pressure blasting system would be best to use with this media? I think there are differences based on the grit size??

Asked by: dwuff
Any of the abrasive pressure blasters would be fine. You may want to buy additional nozzles that are large enough for any media you will be blasting. Soda blasters are designed specifically for soda, which separates them from standard pressure blasters, but they do look the same. Just make sure you get an abrasive pressure blaster.

I have a 1976 GMC Sprint with straight bumpers and I would like to paint them in my restoration. Should I use a glass media for prepping this for paint or is there a better method? Thanks for any advice

Would this work to remove moderate rust from an automotive fender? I picked up a used set of 69 Barracuda fenders that need stripped for repair and paint.

Asked by: Matrick
While the 40/70 Ground Glass would work to remove paint and rust, the use of a Soda would better on the sheet metal. Item #11807 would be a better way to go.
