i trust in the tech manuals and the mfgr recommendations. bottom line is you go by their system or you are on your own. acid must be neutralized by rinsing. each one of my tech manuals reads the same. using acid is nothing new but there is a right and wrong way to use it. use in a sheet metal shop to prevent rust and use for etch in a paint shop are two different worlds.
