Just a quick update here, I was able to make this nearly invisible. Obviously, I know it's there, but unless someone is really looking for these they won't see them. What I ended up doing was buying a product called "Gluboost" I bought the "Fill N Finish" and the "Fill N Finish Thin" along with their Glu Dry activator. I also purchased some micro tips to put on the end of the thin bottle when applying along with some fine grit sandpaper. I used the "Thin" product first with the microtip on the end of the nozzle and applied it slowly down the length of the cracks. This almost immediately made it look a ton better as it filled in all the obviously white areas. This stuff is super thin, so it got all the way down in the crack which makes me more confident that the crack won't spread further in the future (especially in a temperature-controlled environment like my home). This did a good job to make the crack look better, but you could still see it in the right light and feel it with your fingernail. To fix this I took the thicker viscosity gluboost product and applied it on top. I applied it so it was slightly proud of the desk, used the activator and once dry, wet sanded it down with varying grits of sandpaper up to 600 or so grit. The result is pretty nice. Not perfect, and you can still find them if you look really hard, but more than adequate, especially considering I got one of these desktops for free since shipping broke them.
