However, the Beetle Black has many multicolor fibers, where the Protostar seems to only have grey toned fibers. What I'm seeing is that the general colors of both materials is about the same, and close to grey. I shot both the Beetle Black and Protostar at 2sec exposure using a partial ringlight that is my standard lighting for coins, so the relative "reflectivity" shows in the overall brightness. I white balanced off the regular multitone true grey reference I usually use. I also shot one of my Protostar backgrounds. I received my Doodlebug Beetle Black sheets today and did some quick tests for use as a background. If I end up buying any it would be the IR version since it's better in vis and has no IR cliff, but I will probably wait for someone else to check it out first. The Musou flock sheet sounds good but their description of its durability and such are not very encouraging. That said, my preference is to paint internal reflective surfaces rather than use flocking material, so it may be that non-adhesive material will just sit unused, but still good to have around. I'm hoping the Doodlebug is as durable, but since it's not adhesive-backed, I doubt I'll use it for backgrounds, but more for traditional flocking purposes. I've cleaned some of my backgrounds dozens of times and they are still very black. To keep it clean, Protostar will withstand cleaning with packing tape, with minimal fiber loss. That is probably the bane of any of these materials, as dust and such will quickly destroy the effect. In this application it provides a nice 0,0,0 background with minimal processing, provided it is kept clean enough.

I use it as a "disappearing background" for coin photography, where the coin is placed directly on the protostar surface. I like it for two reasons.first, it has sticky back so is good for putting onto surfaces with minimal trouble.and second, it is very durable. Indeed it is available now, so I bought some. I remember this Doodlebug thread and trying to buy it years ago but gave up. That product still seems to be available at Hobby Lobby. hp?t=17917, "Doodlebug cardstock is blacker than Protostar".

I mostly use Doodlebug Beetle Black cardstock, for the reasons described at.
