Have an annoying scratch on my j45
Will this stuff make the guitar explode or anything
BBG, the answer is yes, it will make your guitar explode!
Or more to the point, it will probably end up causing your area of concern to explode into a truly ugly mess - and you will have created it, so it will drive you even crazier than what you have now.
That is a finish scratch. The nitro touch up will sit there in a blob, or series of blobs (no matter how miniscule), and you'll have one heck of a time smoothing it out & making it look like anything besides a hack job. You'll also most likely end up with visible alterations to some of your surrounding finish by trying to blend this area in (because black shows everything). If this were a dent or chip, it would be a totally different story.
Bottom line: Take it to someone who is experienced in working with nitro finishes !!!
If you simply must attack it yourself, the only thing I'd recommend would be to use some Virtuoso Cleaner (light to moderate pressure) on a fine microfiber cloth to buff down & remove some of the scarred finish within the scratch, and follow up with a bit of Virtuoso or Gibson polish to keep any of the cleaner from settling in..... sometimes it works & sometimes it doesn't.
But please, just back slowly away from that black nitro!
