Cramer fugi kit for Silicon work

[Flintstone]

Yes cut mine at an angle. And I agree if you have thin cheap Silicon it makes the job much harder

 

[Time's Ran Out]

I cut mine square and hold the nozzle at an angle.

 

[Dumbo]

Cut at an angle and hold at an angle

 

[Adrian mcc]

I use these draper ones the Silicon is softer and tools off abit better

 

[Paul Smith]

Also cut at an angle.
