I have no experience with the "varnish" finish Specialty uses on their wood, an do not know what it is specifically.

But I can say that the Z-Spar Flagship marine grade varnish that i use, anywhere from 10 to 12 coats, does not exhibit what you describe at all. Even after years of water exposure, no spotting at all.

My recommendation would be to improve the quality of the varnish, and see if that eliminates the problem. On a test component that is cloudy, sand the surface well with #220, and see if the cloudiness goes away. Then apply about 6 coats of Flagship, and see if it looks proper. If that fixes the problem, do it all.

If the above process does not solve the problem, your only option is to strip off the Specialty finish, stain with Zar #120 teak stain, and re-varnish many coats with a good marine product.
