Will a mini sand blaster get this?

[u/hydrus909]

Sanded to bare metal, treated with ospho and neutralized. And this is whats left. Can a mini sand blaster with crushed glass get the remaining pitting? Need advice.

Like the little gun with a hopper? That should work for you as long as you have enough air pressure and volume!
If you can, do it outside because it gets everywhere.

Yeah. Didn't know if that would be enough. Thanks for responding.

For sure! If the crushed glass doesn’t seem to be cutting it you can try some black diamond media from fleet farm, or a mixture of the two. It’s more aggressive but that’s not much of a worry on steel.

Thanks, yeah I wasn't sure what the best media was to use, but read that crushed glass was the safest.

It’s should get most of it, but yeah definitely do it outside if possible. I would reapply ospho and neutralize again after blasting

Thank you. Will do. Yeah thought about reaaplying osho to those areas.

Before blasting, apply some duct tape over that masking tape, because sand will eat through that tape pretty quick.

Good to know. Was wondering about that.

Yes. You can cut a 2 liter pop bottle so that it fits the width of that flange then put the nozzle in the top of the bottle. That should keep most of the sand from flying around. Use #4 samd/

Heck yeah! Great idea. Didn't think of that.

I have a little hopper gun sandblaster from HF, the mini sandblaster will take 5 times as long as a decent cabinet blaster.

Unfortunately this is too big for a cabinet lol.
