Now I'm far too lazy to go with Tony's method effective though it is.

I like the styling of your card model as it has clean lines and just the right amount of weathering and dirt for my taste.
For me speed and a less is more approach is key for my card models so I either don't add rivets and leave the paint scheme to suggest detail.Or I use an older method of PVA glue dotted on with a cocktail stick.Which works well for me on 20-28mm 'scaled' models.(the trick is to mark out small groups of rivets with a pen((round about 10 - 12 at a time)) and dot PVA over the pen marks then repeat once there dry on the next section ,this way you only place rivets where you want them ,also you don't miss any out or smudge the ones you've just done).
I'm looking forward to the Garford -Putilov build, as it's a difficult build ,the circular shapes are unforgiving and very much in plain sight .( I've heard tell there is a mystical combination of profanities once uttered by the modeller will instantly render his work complete and devoid of glue finger prints.If your anything like the rest of us you will try to find this long forgotten combination at least once during each build. Alas no one has found it ,though we try
