PG/VG Myths and legends

[99watts]

Hey there!
I'm still relatively nOob-esque when it comes to lower nicotine/higher wattage, flavor enhancement, and the balance of PG/VG. I know (I think) that PG acts primarily as the binder for the flavoring, delivers the throat hit, and is usually the smaller fraction for the e-liquids I've been seeing around lately. Whats the deal with VG, other than being...what...the flavor itself? And is it more common for people to have a sensitivity to PG or VG?
Im also starting to notice a film on the inside of my car windows...could that be VG? Just curious, Thanks!

Vg gives the nice thick clouds and many people are finding those thick clouds more satisfying. Also the pg gives a tiny bit of throat hit but the vast majority of throat hit comes from the nic. I think it is mod common for ppl to have pg allergies. Unsure about the car windows as I vape with the windows down like I did when I smoked.

when it comes to the PG/VG issues, it seems to be a 50/50 mix on them. 50% say VG causes the "heavy lung" problem, the other 50% sez PG causes the swelling,itching in the throat/sinus area. I myself get the irratation in the throat when I do anything over 20% PG..
and the film... yupperz that is a product of vaping, hard to remove sometimes...

The film on the windows is usually worse in cold weather.
