Yes you do get a seam, you could use a thinner mat such as
a tissue and elemers PVA glue, this also dries rock hard and if
you use thin tissue paper used on model planes or gift 
packaging it can be got to a near smooth finnish, enough so
that the undercoat can all but remove the surface detail.

The towel technique comes from terrian modelling where seams
can easily be flocked. Tissue & PVA can give you a very
fine finnish, I know this from my balsa plane modelling days
where we used this technique to seal the grain on balsa 
fuselages, it should be perfect on styrene.
