I am putting a thin layer (I think) of wash. I water it down a lot if that is what you mean. You only apply 1 coat of wash? I am putting 2-3 coats on. If the slump is only to 677c that is more than your slumping schedule is and I pretty much go by your schedules on here.
I am totally self taught so all this is so helpful. The schedules have been the hardest thing.
