Discussing religion, politics, sex, wheel landings, and whether to prime in polite company is not advised.....

If corrosion is the concern there is another option that has not yet been discussed:

Quite a fantastic product. I will warn those that polish though, when you use ACF-50 it will creep out of every crack and crevice for a few days after application. I used this on my last Sonex by ordering the aerosol cans and applying it as I put it together. It can be sprayed or fogged into the air frame. Needs to be applied every two years (preferably at annual) and has very minimal weight.

I am not priming my build... except for the fact that I did prime my wing spars with inexpensive rustoleum aluminum primer (not etching.) Doing so on the spars was more of an experiment/why the heck not sort of move. I'm still not convinced it's remotely necessary.

As far as resale goes... as many builders that (it seems to me) prime their aircraft, I'm sure the expectation of buyers is tenfold that priming is necessary. So I imagine there is a resale benefit to doing so.

LOL, I guess in that sense it's like a self-fulfilling prophecy.

I primed the internals of my sonex, yes its a bit more work, yes it adds a bit of weight and yes, it may be overkill. I did it for me no one else.

At the time I built it I lived quite a long way from the coast so there was no real need to prime. 18 months ago I found myself relocating for work. The plane and I are now near the coast, real near. I am glad that I primed the internals but now wished I used duralac on all rivets.

I say each to their own. If you want to prime go ahead if you don't then don't. Simple as that.

The stuff that Dale mentioned sounds like the same stuff they use each annual here on a C182 seaplane.

Thanks everyone for the info and advice. I think I'll just stick to the rattle can, it really can't hurt anything-even if in the long run it doesn't help. Like was mentioned earlier, if I ever go to sell I'll have the novelty of saying "Yea, it's been primed".
