GF recommends a MINIMUM of 3 coats. But getting crazy with the # coats is a recipe for disaster.

Unless I missed it in their tech doc ( there isn’t a maximum coating limit. Some information can be gleaned from their 1MDFT (minimum dry film thickness, usually given in mils) comment. I think the average sort of wet mil thickness would be 3-4 to achieve a 1 mil dry.

Anyway, you can do some grain filling by wet sanding with this product after the first couple of coats. Instead of using water or MS to lubricate some wet-dry paper, use a little of the finish and work up a goopy slurry which can be forced down into the grain. Won’t be a 100% fill on most things but can help a bit. And can also fall into the fallacy of “if some is good, more is better” so don’t over do it.

And build coats with gloss then finish with satin or semi-gloss if you want to tone it down a bit. Generally has a cleaner looking appearance.
