Liquid Blue is pretty thin. Way thinner than White Diamond or Black Hole (at least my bottles are). No issues with it, however.
I'm to about half bottle. It does look like it separated, but a very good shake blends it all back (and back to split after sitting a bit). Still, it works. Some applicators may soak up some of the product. Others, not as much.
On some applicators, I'll just run a small bead of product from the bottle straight onto the panel. Then take my applicator and spread it fast. Then I'll work it. Seems like extra steps, but it all happens way fast. it's why I tend to reach for Liquid Blue more than paste waxes.
I recently picked up a second bottle of Liquid Blue. That's how satisfied I am with the product.
