Im wondering why this would not work to prime a fender or hood using etching primer. What you think? Thank's

It'll possibly look like a giraffe diarrhea splattered on it, though.
That's probably not the best description, but I've sprayed all sorts of stains & primer & paint through those 'Wagner-type' airless guns. If you just want to coat the metal, it will work just fine, but it will sort of dry to a leathery texture.
Subjective statement: I know you asked if it will work; it will, but it will not look very good.

Moth automotive solvent based paint do not play well with plastics, melting them. Same can be said for any seals inside the unit.

Brad Nothing a good belt sander couldn't take care of though... Actually a simple RO pad sander and some 80 grit work better, but if it turns out like TANNED leather, well maybe the belt would work.
Give me ambiguity
or give me something else

The main reason that comes to mind is that solvent based paints have a much lower combustion temperature and will easily ignite when coming into contact with things that spark! IE, an electric airless sprayer. I do have an air operated airless sprayer ( Yeah I thought it was funny too) that is used in the automotive world. It was about $3000 for the set up that we used in a high production industrial urethane job.
Buy a decent gun to spray your primer with!
