Etch and Acid Etch, much the same, just that different brands use the different terminologies, they almost all contain some phosphoric acid. These are
used for their superior adhesion to metals plastics etc, and do actually 'etch' into the surface slightly to provide that adhesion.
Primer - use over existing keyed paint, or etch primer to create a perfect base for colour.

Bump an old thread, but can you go straight to a colour coat over etch primer or does it need a high build primer coat over it?
I'm just looking into painting my robin hood stainless monocoque and was thinking I would use etch primer then a stun black for the interior and
for the exterior I would do a more thorough job of etch, high build, colour, clear coat.

That's all I have ever done, on stainless, ally or GRP. Don't sand between coats (except for the clear coat), apply coats between 15 to
20mins and it will be fine
