I am curious if anybody has tried the eastwood kit that converts your pressure blaster to a soda blaster. Does it work as well as they say? Also, it appears to be a few fittings, and a length of hose, any reason you couldnt make one for far less money? Any help would be greatly appreciated.

 

Also interested if anybody has tried the retro kit. Reviewed the video on Eastwood website and it appears the kit is designed to work with both coarse media, and soda, it's just a matter of turning the shuttle **** to the desired outlet. If that's the case, not sure why yu could not use the existing plumbing and just add the shuttle ****, 't' fitting and couple different dia. outlets. Have not checked the size of the existing outlets, suspect 3/4" and would need to add 1/2" nozzle outlet for the soda. Anyhow, food for thought!!

 

Here is one issue to consider with soda blasting. If you do not completely remove the soda from the seams and joints,then paint over it, you will have problems down the road. The soda can suck up moisture from the air and expand, causing the paint to fail or sometimes the seam to blow apart.
Not trying to tell you not to use it (its better than sandblasting) but I prefer either ground up walnut shells (you can run thru a sand blaster) or the little plastic shards.

 

I havent tried the walnut shells, but had been thinking about it. Anything I should know?

 

Not really any different than sandblasting. Its just a different media. If there is heavy rust it will not remove that, but then soda and plastic wont either. Nice thing with the walnut shells is you can do it outside, spread the shell dust around and forget about it because it will just breakdown over time.
