Thinking about this - primer as finish coat?

I think you would have been OK with just gloss-coating the white primer.  Primer by its nature is porous, so it tends to absorb lots of unwanted things, but with a clear coat over the top of it, that would take care of that issue.

I've done it.

I don't see why not? I have often used Tamiya white primer asa finish coat for the underside of US Navy aircraft... By the way - IMO it's better to apply a layer of grey primer and then use white over that. This way you get a vey good white surface in two layers. If you start with white on a model made from different materials the differences may show through and the second coat of white might not be enough to even them out.

Hope this helps - have a nice day

Whites & greys give me fits. I primed in Tamiya grey liquid surface primer air brushed and the decks were Tamiya acrylic neutral grey. That was ok. But when I went to brush the rails Model Color gloss white, the grey was showing through. So I stripped and then primed in Tamiya Liquid Surface primer white, air brushed. Then taped to spray the rails  VMC gloss white. A lot of taping for tiny parts , but so far ok. Now have to reshoot the decking. 

So far, white primer and white air brushing or brushing - hard to see white on white. 
Grey primer under white - see through...  Always something

Oh!

       I have to chime in here. In my last two commissions I used "Rustoleum" Pearl Grey primer as a finish coat. Just the right matte finish(No Glare) and easy to touch up. Also readily avaoiable. The White used on all overhead surfaces as per U.S.N practice(Peacetime). Overheads white, Hulls and all vertical surfaces Grey

I frequently use red oxide primer below the waterline as the finish coat.  Many fresh-water ships use red oxide paint on the hulls- it is a very stable and weatherproof paint (look at how often it is used on barns).

Car nodelers building rat rods also use a primer as finish coat on body.

As I mentioned above I have done it with no problems and good results, Vallejo primer,washed weathered,filtered,and decaled.

Why not?  On my USS Pennsylvania 1935, I used the light gray Tamiya Fine Surface Primer, and decided it looked pretty close to the color I was shooting for, so I left it as my finish color.

If it looks good to your eye, then it works.

ok, that does it for me.  New trick in my bag!  Tks all!!
