Hey folks, just noticed this crack under the hotcoat starting at an old fix (not my handiwork) on the bottom of my nose. I can't feel it with my nail at all so not in at least the top of the hotcoat. The first few inches beside the fix I can maybe feel the slightest hump when I run my finger over it. We're talking barely. What am I dealing with and what should I do to remedy? I've already fixed a bunch of crap with this thing, looks like I'm in store for some more work! Thanks for any advice in advance!
