good info. ThanksRodStRace wrote:First, there are a LOT of soda blasting videos on you tube. Check them out.
Second, the guy only touches on after treatment. Washing with water alone is not enough! Do some searches and you will find that it needs to be neutralized with a vinegar solution and some scuffing is good too. This is so the primer has something to bite on.
Third, I soda blasted a friend's car and it still has some soda clumps hiding in corners. You want the shell to be completely empty and be able to flip it around to get all the soda out.
Fourth, I plan on doing my van soon. We used 12-15 50# bags to do the outside of his Challenger, to do the inside and outside of mine, I expect at least 20 bags. Pricing is usually on a pallet basis. Check your local supply.
Fifth, the reason I plan on using my friend's tools to do my own is that I was quoted 900 for the outside, 900 for the inside ($1800). It's hot, messy, dirty, and you need to develop a touch so you don't waste material or harm the body.
Sixth, they also skip over what powers the blasting pot. Even a 220V 2 stage compressor with a 60 gallon tank is not going to be able to keep up with the demand. That is the absolute minimum needed, and you will have lots of down time letting it catch up. My friend has a gas-powered trailer mounted compressor, the type used to power jack hammers.
