We just started using this process in the Submarine Fleet. The control with
a AQUAMISER is great you can dial in the amount of paint that you want to
remove but more importantly the bicar. has been shown to actually pull the
oil out of the metal substrate to allow better bonding and it doesn't
destroy the "tooth" profile of the material. Also there is a process called
"Sponge jet" that does the same thing. I offered my TR-7 engine as a test
platform but they just shook their heads. Something about too oily.
