40LB Soda Blasters

[Lionelgee]

Hello All,

Thanks for the replies. The Soda unit I posted up earlier is a dry powder version.

I suppose for heavier stuff a media blaster like this one could be used and betwixt them both a very handy range of jobs could be done. http://www.ebay.com.au/itm/New-Porta...item2ee71f4bb4

There are smaller gravity fed media units available however they have very limited capacity. http://www.ebay.com.au/itm/HEAVY-DUT...item43c81d387c. I reckon that they would run out just as you get into the swing of things. Then you would have to take off all the safety gear and fill it up again all too quickly.

The blurb about dry soda blasting says something about how it forms a coating on bare metal that prevents rust and how this needs to be removed before painting. Therefore, if there is some time between cleaning and the opportunity to paint then they reckon that the surface should remain rust free for a while - notice the words "they reckon", "should" and "for a while"

I have a couple of engine blocks to clean up (soda) and wheel rims (Media) followed by soda? Maybe spot bad rust with media on the rims then finish off with soda?

Kind Regards
Lionel
