Hi, Tony --
Auto body shop supply stores here sell products
under names like Metal Prep, which is an acid
cleaner. It's probably better than just sanding
and virgin solvent, as I figure body shops
wouldn't spend the $ if they didn't have to.
You may not see Mach .78 with that Boeing product
<g>, but I hope it's for steel and not a
water-borne item. I've read complaints about rust
using water-based "zinc chromate." Important
thing is to coat immediately after cleaning.
