Which percentages would you recommend for a Smok tank?My Priv v8 is still going strong after about 4 months of use and no paint ever flaked off. My friend owns a GX350 and the paint only started coming off when he dropped it pretty bad so if you take care of your mod it will look brand new almost indefinitely.
The coils are fine if you are careful aswell - don't take those extremely long hits and use Juices with less VG. There is also a video on YouTube by RiP Trippers where he shows how to modify your smok coils to reduce/eliminate dry hits.
