I spray. I've done it & had good results, actually. It depends upon the type you use. I use Windsor & Newton matte artist varnish.
We used cellulose car lacquer out of a spray gun.
We had to do it in the garden and I had all these sheets of cards attached to bits of string and tied to a frame...
It was quite good fun for an afternoon messing about, but in the end it wasn't worth the hassle for all the ones I had to do.
Nice effect, cards stayed flexible, just so much trouble, and it made the card slightly transparent, and I couldn't use thicker card because it wouldn't go through the printer properly.
I'm afraid I can't say what weight card this was as it was ages ago, and anyway it wouldn't mean anything.
Sadly we have been metricated and it was in gsm (whatever that means!).
So I laminated, and although it made the cards sort of plasticy it did make them thicker, which was good.
