Quote:I wonder if there is a difference between 4290 Ultra Flat Camouflage Black and 1602 Ultra Flat Black?... I think one benefit of Flockboard is that its texture scatters light better than paint, but I don't know which is better at not reflecting light. One thing for sure, Flockboard is very black.
Quote:The Joanne's Premier Velvet sounds interesting - but how to get it secured inside larger tubes?
Quote:When using rattle can flat black spray paint inside of scope tubes - I just lay it on thick and not worry about runs or buildup. The end result is a sand-paper like texture which I'm sure helps in light scatter. But, when painting components, such as secondary holders, spiders and even nuts and bolts inside the tube holding down finder rings, focusers, tube weights and so on, a good flat black is very important.
Quote:There are a lot of plus and minuses for using paint or flockboard depending on the application. For smaller tubes, I think paint is the way to go - it costs less and is quick and easier to do.
Quote:I haven't noticed any shiny speckles on the Flockboard I installed, and I use a lint roller to remove any debris that might land on it.
