Does the dye get sucked into the flow bench? Does it cause any problems or is it messy? Thank you.

It’s alcohol based so it dries pretty quick.

I hate to admit it, but I‘ve used red and blue paint because it was all I had at the time and I was ready to test.

And it worked. I’d rather use dykem though.
