I haven't seen this discussed before, so hopefully it's not just me. I've been using Polly Scale flat coat on my aircraft and armor, and have been very pleased with it, except for one thing; every bottle I've ever used had tiny black specks in them. I try to remove them, but invariably I get some on my model when I airbrush, requiring me to lightly sand them away and coat again.

Has anybody else experienced this? It doesn't appear straining would work, since the flecks are so small, but I've never tried it.

I have seen this as well, on polly S dull and satin clear coats...never really bothered to try and remove them as most of my planes are a dark color..No explanation of what they are tho...
