I dabbled into some soda blasting today and I have to say I'm a little disappointed with the results. I used the "jam an air blow gun in one end of a tube and stick the other end in a bag of baking soda" method that so many people on the internet seem to have success with, yet I found it to be very ineffective, slow, and it uses a LOT of soda. I used my buddy's 30 gallon, 6 SCFM @ 90 psi compressor, so I don't imagine that was the problem...? Disclaimer: this was just an experiment to see how well soda blasting worked workout spending a bunch of money. Hell yes I have pink duck tape. Here is my setup: Oil pump driveshaft to keep the tube straight in the bag, haha. Here are my results: Before: After: Left side is unblasted: That area around the Ford logo took me about 20 minutes and at least 1.5 lbs of soda. Not only that, but because the process was so slow, my gun kept freezing up and then the soda would jam. Ambient temp was in the 60s. Thoughts? Is this just how soda blasting is, or do I need to rethink my gun?
