Looking for idea's to hide window screws

Nothing wrong with sika or 3M or lifecaulk. They are all knife-grade adhesive sealants

Sillycone has no place

I heard sikaflex requires primer.
I ordered Sikaflex 295 UV and Sika Primer-209N. Hopefully they are good.

Look at the msds sheet for the primer. And check the sika chart
