remember rosko, soda blasting is good for paint removal of clean metal, it does not remove corrosion like a good old fashoned sand blasting will. The upside it is does not heat the metal and the surface is most of the way preped for painting. The best thing I can think of is honda plastic parts - sand eats them like crazy.

That being said I have tons of stuff you can soda blast, a stack of sidecovers alone.

If you have heavy rusted stuff come over to my place and blast it with aluminum oxide or walnut shells. Between the two of us we should have the whole place covered.

Oh and build the box big enough so I can get car parts in, Please.

I guess I should have been clearer, it will neutralize and remove rust, it just takes a lot longer.

Not that I know a lot about it but isn't there either a health concern for soda blasting (a respirator is needed to prevent lung damage) or a risk of explosion or flash fire from the dust in the air? Then again I guess you could say the same thing about two part auto paint....

Hey Geeto - what would work better on a T500 crankcase? Walnut shells or soda blasting??? I need to get the race bike case cleaned up as my crank is at the rebuilder's now......

EDIT - Or I could read Rosko's post a little better and see that he's got the coveralls/repirator/air handling thing covered already....

I guess you science teacher never showed you how to make a flour bomb jim. Any particulate matter suspended in the air is suceptible to explosion when compressed in a container. All it takes is a flash flame and boom!. when I was a kid we blew up a lot of paint cans and garbage cans with sacks of flour. It doesn't matter the material (which is why most sandblasting cabinets have vents) but soda does touch off a little easier than say aluminum oxide (although aluminum oxide has a hotter flame front). As for a health concern, yeah they all do. I could not tell you the crap I used to cough up back when the corvette shop had me wroking the sandbalster for 8 hours a day for days on end.

Personally, I know you jim and soda is what you want. shells (from here out I am just going to call it sand) will give you a little bit of a rough texture (like matte aluminum) that you will have to take one step further to make look like normal aluminum. Soda will give you a nice natural metal finish that is smooth to the touch and has a light sheen. If you are painting the cases then sand, if you want to just clear the aluminum then soda.

call me jim I'm sure we can get this taken care of for ya.
