Silicone around uPVC windows?

[NewShoes]

Hey all,

I am soon going to replace the failing silicone around my uPVC windows. From the look of it, the windows have been fit poorly and some have large gaps between to the frame and brick. Due to this, I think I'll need quite a thick bead of silicone, is it best to just carefully run a thick bead and leave it as is or try to smooth it down? From past experience, smoothing a a thick bead results in a messy looking finish.

Cheers,
