I read a lot of posts about priming stock pre-made coils. Here's my method:
I don't.

And I've never burnt a coil or had a dry hit in either my Nautilus Mini, or GS Airs.
When I first started vaping, I read a lot to make sure I did the right things, a lot of sites, and people, said prime the coil by putting juice in the wick holes. I did this at first, but one day the engineer in me realized that doing that is no better, in fact if you use only a few drops in each hole not even as good, as just putting the coil in the filled tank, taking a few hits with power off, shaking it around a bit to get the air out, and letting it sit 5 or 1o minutes and then drawing a couple times unpowered and then start at low power, around 8 Watts, and take gentle short puffs the first few hits, then I''m good to go at whatever power I want.
Think about it. If you are putting drops in the coil head, a few drops on one side slot or hole, a few on the other, I guess if you are patient enough, you will saturate the wick in maybe 5 or 10 minutes or so, lol. instead I get a lot more juice up in the wick taking a draws unpowered with ALL the wick holes sucking in juice due to the vacuum being pulled when I draw. A lot faster and more efficient than letting only the wicking action of the cotton against ambient air pressure slowly saturate the coil as you try to pry drops into those little holes.
If I were going to going to prime a coil, I would use Cheechako's method, that way at least you get the inside of the wick around the coil saturated first, and i would probably put 5 or 6 drops or so. But i don't prime because I don't have to and you can't make me.

Well actually I do prime, but i do it by taking unpowered draws with the coil in the tank. A superior method. *Ducks* lol
