IMHO, methyl alcohol is a pretty mild solvent, and also probably not strong enough to remove cured spray paint...it's the small amount of MEK they add to make it "denatured" that I would worry about. Goof-off (a solvent blend) and acetone are much more harsh solvents, but more likely to do the job. I would try those after you try the alcohol but before you use any of the "safer" strippers...just been my experience. And use gloves and good ventilation for any/all of it.
