across a discussion of it at an autobody supply website and many
people there have used it for metal etching, rust conversion, rust
prevention. It is also said to assist in cleaner welds. On top of
all this it is said to be completely safe to use.
I am not affiliated with this company at all, just curious if anyone
here has used it and whether or not it lives up to it's own
hype....any comments are appreciated. Here is a link to the site
