I waited about a month for this stuff to get here. I think it came directly from Japan. A lot of folks on my various Facebook groups have been using it as a primer. I have bottle of the Mr. Surfacer 500, but that is more for gap filling. The higher number equals thinner stuff. As much as I prefer spray primers, it's been difficult lately to go out and spray things and I am really not that crazy about Gesso. This might be a better option for a brush on primer.
