Really looking forward to these results. I’ve been staring at those Filmbariek rollers for a while. I thought they were all foam, which made no sense. This roller you found makes more sense. I still don’t understand why they have to be rollers if they don’t spin.
I’ve been trying to find a post I saw a while back of a guy who made is own wetgate using film cleaning cloths. I’ll be sure to post it here if I can track it down.
