copper slag blasting

That is what I use I think it is worth the $ the sand does not take down that fast and you have to make a few passes

Around here, on fully assembled tractors, some people have been using soda blasting. Soda doesn't cause the trouble that sand does when it gets in all the seals etc. Soda also is easy on old thin sheet metal making it perfect for antique cars. They claim it changes the surface of the metal and you don't need to paint immediately like you do after sand blasting.

Anyone ever tried it or have any experience??

biggastractor - No .. but I saw a Soda Blast guy driving around the other day with advertising on his vehicle. I looked him up, and he's only a few streets away from my shop.
I have an Ingersoll Rand Type 30 vacuum pump that I just bought, that needs a good clean up .. I'm going to have a chat with him this week and see what the score is. His advertising blurb is pretty impressive .. and he talks my language .. inexpensive! 😄

how does blasting with glass compare with soda.

I saw the result of soda blasing on an alum truck body, it was perfectly clean, like the paint was just wiped off. And it went all the way to the glass with no masking, and no glass etching. Have no idea how well it would do on bad rust,,,

Soda blasting is a very mild form of blasting and that is why is is better for thin sheet metal. Its true benefit is that it nuetralizes the rust and that is why you do not need to paint right away. But do not think that you are going to peel away the layers of rust and paint very fast with soda.

My opinions of glass is very similar to that of sand. They both work fery well but tend to be picky of air pressure. If you set the air pressure too high it just shatters the sand/glass.

I like Aluminum oxide or a similar copper product for fast and effecient stripping.

Just my 2 cents worth.
