Hot spot issue after adding juice?

Sounds more like a wicking problem than your coil. What kind of wick are you using- mesh size, wide or narrow, solid/hollow?
You can tell for sure if it is a juice flow issue if you put a few drops directly on the coil. If the hotspots go away, you have your answer

500 and it is slightly hollow (tight as I can seem to get it and semi tight in the dud wick hole). It wicks juice fine, even if it did dry hit it should not short/hotspot right?
Did you try the juice test?
Glowing coils doesn't necessarily mean a short. People use the terms interchangeably, but they aren't...
If the coils glow evenly when dry, then you either have a wicking issue or possibly too much power.
If you get bright, coil-bursting hotspots, then the juice has nothing to do with it, and you just need to adjust your coil. It's harder with a wet wick, but can be done.

What I did, was dry fire till even glow and then drip onto the coil/wick and fire till dry again to see if it would short which it did and e1/e8 error codes.
I did this test after a few days of metal taste vape on a few diff wicks/coils that fired even when dry.

do you run a loose positive post screw?
Eventually, most shorts will disappear with time just because of oxidation. I have never heard of eliquid exacerbating a coil, much less causing shorts...are you sure you're not vaping electrolyte?

I'm going to guess either my coil is wrapped too tight, or my wick is not oxidized enough. I said screw it and went with a carto tonight but I will mess with it again tomorrow.
Yeah, im going to give another build a chance and if its still acting up I will post pics.
Had this several times myself before, by some unknown miracle, I got much better at the wick 'oxidising' lark - dry firing 1.6 to 1.8 Ohms coil on even 5v, get all coils glowing even and the right reading at the meter afterwards, but soon as any juice hit the wick/coils, I'd get hot spots and shorts and the meter reading afterwards would show it too -
- Seems that if the coil was at just-right tightness around the wick, but the wick's oxidised coating wasn't thick or even enough, that the hot coils on hot and dry wick were fine and didn't short, but soon as the coils got cooled with juice they tightened up on the wick and created a short (different heat expansion rates between coils and wick), or at least that's what it was for me - I didn't get this issue sorted properly until I got better at oxidising in the wick before wrapping the coil.

I just did it 'more' - I started by doing the whole strip until it just glowed orange and slowly raised it out of the flame to cool slow, before rolling it - this just helped it roll and keep its shape far as I could tell.
Then after it was rolled (I rolled once, unrolled and rolled in reverse as many seem to do), I gave the exposed edge a really good flaming and burned or scraped off any glowing strands (I tried the edge fold thing but it didn't work for me - got hotspots under the fold ridge), I gave the whole wick a really good heating up and plunge under running cold tap one time to stiffen it all up slightly, then gave the coil end of the wick 3 really good heatings with the mini-torch until it glowed a good orange colour, then plunged and dried and repeated a total of 3 or 4 times.
In the end it had a good, smooth matt black colour to it, but it was not 'crispy' or brittle - haven't managed to make one go that way personally, but I haven't actually tried either!
It seemed that although I'd thought from what I'd read, that I was perhaps overcooking the mesh previously, it seems I just was undercooking - wasn't actually doing it enough - for me 'brown' = useless and underdone, but 'black' = done perfectly allowing me to wrap very tight (am able to do them too tight in fact) coils without much issue.
As someone pointed out to me here recently (regarding wicking in RBAs) it likely has summink to do with some kind of voodoo - suddenly everything just seems to start working right and coming together and you're left feeling less than certain what has actually changed, heheheh...
be well!
