I'm assuming that you are applying this to an aircraft model. If you are, I would reccommend that you leave out the doped linen and apply the silver directly to the model. On a 1 to 1 a/c, the minimums are 3 coats of clear dope applied over the fabric followed by 3 coats of silver dope. All 6 coats are supposed to be applied with a brush and can be lightly sanded between coats. Those are the minimums, but most people apply more coats because as the more coats you apply, the smoother the finish is. The thing to note however, is that after the second coat is applied, the doped linen is no longer showing.
I don't use metalizers to represent doped surfaces as they are made to represent metal surfaces. I would recommend shooting MM Flat Aluminum on the surface topped by a semi-gloss clear. Silver doped surfaces tend to weather very rapidly to a dull finish.
On a side note, I always sand the "fabric" weave molded on the surfaces by the kit manufacturers off. The weave is so small that you wouldn't be able to see it, the only clue on a model would be the sag of the fabric. (and depending on the internal structure of the cloth covered item, there may be no sag - you'd be surprised the number of people who don't know the rudder on a P-51D is fabric covered)
