There is really little point in applying a coat of gloss first. While some painters insist that the gloss is tougher, in actual practice with most modern varnishes there is so little different that all you're doing is adding one more step where you can potentially screw up the model with a bad batch of varnish.
if you really feel the need to varnish your models (I've
never varnished my gaming models, and nearly 20 years of use hasn't hurt them perceptibly, aside from a little wear on some of the older metal models... if you're using decent quality acrylic paint there is little need, and it can really kill more subtle shading) then invest in a decent quality craft spray, and try it out on something unimportant first, as many varnishes change the colour of the paint. Cheaper hardware store sprays are likely to add a yellow tint to your paintjob.
