Continuing the discussion from Dexcom G4 sensors are driving me crazy! Help!:

Go for it! I’ve been punching through Skintac for nearly 2 years now, and have never, ever, had any problem.[/quote]
I don’t think I was clear enough in explaining that I am not using a Dexcom as you are. Oh, well.
I do use the Medtronic CGM and their Enlite glucose sensor. So I’m really not sure what might happen if I tried to insert the sensor through an area I’ve prepped with either Skin Tac or Mastisol. I have my doubts about whether the sensor probe sheath is completely encased by the introducer needle and thus more likely to be protected from possible contamination.
I have never tried to visually inspect the Enlite introducer needle simply because my eyesight is not all that good. Still I might try doing that tomorrow afternoon when it will be time to swap out my current sensor.
The only other thing I have to go on is the bit of “needle porn” in the pic below. It shows a slide from the 2014 Medtronic Diabetes Advocate Forum conference which compares the size of the Enlite introducer needle to the previous Sof-sensor (aka “Harpoon”) which Enlite replaced.
In the slide it appears from the needle cross sections that even though the sensor probe is technically inside the introducer needle, a portion of it may still be exposed. Assuming some portion of the probe sheath is “exposed” then I am also not sure how much damage would follow if any of the exposed probe sheath were contaminated from contact with a skin barrier.
