We have feathered drafts and use Eqyss Micro-Tek spray on their scratches - nothing else affects it at all, but the spray makes it disappear in a day or two.
I have heard of using Micro-Tek on thrush, but haven't heard from anyone who has actually tried it.
Has anyone used it for this? Or know anyone who has? Does it work? How did you apply it (shampoo soak, spray)?
