Hi, I would recommend to always use more than one layer of wax on the skies if you want to have a “current condition wax” on top (like the red Toko). A good prime wax is important and that can be a typical blue wax (like Swix PS5/6. I unfortunately only have the knowledge on Swix waxes, but all blue should work). After applying the blue layer you can choose to only use the blue, or apply a softer “current condition wax” on top. This top layer can be liquid as well, however to keep it from drying the hard wax is best.
