Eastwood's soda blasting conversion kit

[scherp69]

Has anyone tried Eastwood's soda blasting conversion kit: http://www.eastwood.com/soda-blastin...o-fit-kit.html I priced out a local guy to do some blasting to get my doors and fenders done but he wants $140 an hour. I already have a pressure sand blaster and was thinking if this kits works well, I can do the doors, fenders and the shell myself for only $130. Any thoughts?? Thanks in advance.
