Is that 'silicone' as in 'Of course, I'll put something to weatherseal the penetrations'?,
or,
'I'll use silicone'?
Interior/sanitary/vinegar silicone does not have good unprimed adhesiononto timber or PVC.
Building/low modulus silicone also benefits from priming.
Could I suggest the Soudal Fix All (Toolstation 61251)
or Fix All High Tack, (Toolstation 84704)
If £6+ per tube is a bit much,
the solvented Gripfill (TS 79360 £2.28) will do an adequate job.
Other suppliers are available,
TS catalogue was to hand.
