I have had mixed results with soda blasting.
Over all it can help with an amazing finished surface. There were a few issues one should consider.
It is very difficult getting all of the powder residue out of the crannies. It keeps showing up when you least expect it.
Cleaning the residue and neutralizing the metal is VERY IMPORTANT! This step cannot be rushed.
No matter what type of paint you use it will not adhere to any bare metal that has seen soda unless it has been cleaned and prepped. The paint will peel off in huge strips.
I had a horrible first go around with it. I had to start over in a few sections. Inner cab, Bed. It was very discouraging. After that however things went great.
For deep rust soda isn't the best choice. You want to switch it up here and there.
As for all of the detail areas in full view there's nothing better than soda.It does a great job.
You will need quite a bit of air pressure to run the bigger blasters as well as an air dryer. The soda will clump easily if it gets damp. This will clog your blaster. I would also use a full face fresh air respirator.
Soda also works great on degreasing.
I have a blaster that holds about 100 lbs of soda good for bigger areas. I also got one off ebay for about 100 dollars that takes less air is portable and works great for smaller jobs.
Soda is expensive about 40 a bag.
It will eat through bondo but not rubber.
Soda will also wash away with water.
I'll try to post some pics of some of the finished areas as well as some of the spots where it wasn't cleaned properly
