I'd say the sanding marks, fiberglass show-through, and lack of complete color distribution are fairly typical. I've seen all of the same on several of my swirls. The sanding marks do show up more on the dark tones. Larger patches of solid color here and there do happen and both sides don't always match, nor does the front half always look just the same as the back half. Then again, I've had some that were "swirled" quite thouroughly. You never really know how it will turn out, but if you don't like it, there is always paint. McMillan even says so on their website.
Some photos would help your thread also.
