I got a little air erasure for my airbrushing and love it (for airbrushing) but it etches glass reeeeeeally slowly. I was looking at a 2 in 1 abrasive blaster and soda blaster. Can you etch glass with baking soda or do you have to use an abrasive? Any suggestions on what I should look for?
Let me add that I want to start doing a bit of glass etching on hot rods/ show cars and am also wanting to start etching designs in polished chrome, stainless, aluminum, etc...

I would be surprised if someone wanted you to etch their show car as it would ruin its value! Sandblasting is the method I am most familiar with though. Using a plastic stencil.

when i was doing this i used aluminum oxide. paashe air eraser and it worked just fine however i did step it up to a large paashe with a blue handle LAC#3 it really covered some area
this is a fun hobby. the results are awesome. there was just no market here for it

I've already had a few requests for this lately so that's why I'm asking. I know it's not a huge market but we are trying to become a sort of 1-stop shop here because no one else does this kind of stuff. I figured it can be used on polished exhaust systems too on hot rods and motorcycles.

Naw, soda doesn't work. Tried that. Aluminum Oxide. Sigh. BUT I will have the frigging freshest smelling fridge for a lot of years! Posted by Kelsey Dum (Member # 6101) on :
Hahaha... got a few extra pounds of soda there, Deri? Thanks for the answer. I like the idea of the 2-in-1 blasters. We can definitely use a soda blaster for small parts we paint and the abrasives for the etching.

oh yeah, hit a sale when the ide spark was fresh

works really well for etching glass. It's heavy so you don't need as much air pressure to do an effective job - more momentum I suppose.
Doesn't seem to create near the dust cloud that other abrasives generate.

Marilin, any idea what that is rated at? The Alum Oxide I am using runs at about 150 grit I believe. I am having a few issues with it going through my Paasche. TYIA Deri

Deri, I had a paasche air eraser years ago, 220 grit was recommended for it, could also be moisture problems and humidity

Does Canadian Signcrafters carry 220 grit Pete?
Posted by Pete Payne (Member # 344) on :
I'm sure we can get it, anything for you Deri!

Deri, I just etched a woman's car windows with my Paasche air eraser, & it clogs up, always has. A pain in the butt! It was not even humid, & it came with a moisture trap on the line. Don't know why. As long as it blasts straight & clean, it is wonderful, but it rarely does. I used the fine aluminum oxide.

Bobbie ... you need a air/water seperator such as :
