Skylights Whats your WFP Technique?

Suddenly I m missing a lot on skylights , when my method has nailed them in the past. It may be that my preferred Gardiner flocked brushes have worn just enough to miss some lines up there. I pre wash the skylights with double dose glass gleam 4 and a 90 degree porcupine 18" sleeve, then re -agitate with the flocked brush on a 90 degree gooseneck. I turn the sleeve end down for the lower few inches of the glass , which is always the dirtiest. Agitate 2x with WFP,then rinse , off the glass 2 x. Thats my method, and it worked well for a long time. But its missing now. I ll swap out my brushes and see if this improves it
Whats your method on these ??
