Is that ferric chloride " the acid " to use for etching prior to painting or just your favorite. I used sandblasting metal parts in the past, yet my small sandblaster ( dental tech) is insufficiant for larger pieces

Chemical machining is acid-etching is rapid oxidation of the metal. I acid treat all copper bearing alloys and aluminum to microscopically pit the metals surface which acts to increase the surface area of the work and to provide 'tooth' so that primer will bond better to it.

Yes, when I photo-etch I use Ferric Chloride acid, heated and agitated. To prepare surfaces for primer I simply brush the stuff on till the oxides form (a darker color than the metal), rinse the work in fresh water, scrubbing off the acid, followed by a dunking in fresh water doped with baking soda.

Beautiful boat David! Weapons installed maybe ?

Nope. Not this one.

Did so, on this one about 20 some years ago.
