Never seen that before, how long before you spray the second pass?

Also to add.....when spraying stiff the mx is not mixed thoroughly and you might have and different shades and shapes .This all can happen with wet gear too caused by quick suction.

Yea I’d say it’s to stiff, first and second pass don’t bind together well enough.
Although I sometimes get the odd dark patch with parex especially g20.

Odd times we get them can’t work it ,use to happen when we had the diesel as well

Had a lad trowling the ribons out soon as they hit the wall then another ruling off and we had no marks at all
