Grit Blast Media Recommendation

[ford38v8]

Two tips:
Keep the media bone bone BONE dry.
Always use soft media for anything with bearings 'cause sand gets everywhere and you never get it all cleaned out.

Most of the time I have used #80 silica sand from the local Masonry supply company.
Most of the stuff mentioned and to be mentioned will work well for general
use but to me it was the availability and the cost.
Another factor that will effect how good it works is what you are using for an an air supply.

And make sure your air supply is dry. Make sure you air compressor is big enough and that will somewhat depend on what size the nozzle is. Air compressor that is too small meaning not enough CFM's will make the air hot and hot air will keep water moister in a vapor until it comes out the nozzle then it becomes water. You will need a good water separator. You also need a long air line so the air will have time to cool off before going through the water separator.

That is great advice!! I did some blasting in my driveway in subzero weather while in AK. thinking wouldn't be a problem but it kept clogging up. Thanks Marvin!!

Aluminum oxide is more aggressive than glass beads in my opinion. I have used glass beads to remove rust from a number of parts. It typically leaves a nice smooth finish on the metal. The more you use the media the more it breaks down until it is more like a sand then glass beads. Mixing together with new glass beads will give you a good blend for removing rust on parts you want to be careful not too damage the finish by being too aggressive with the cutting power.
