I would recommend testing both the original paint and the touch up paint to see if they are solvent sensitive. Otherwise you might end up with a real mess on your hands if you try painting over it with the wrong paint. If you’re lucky the paint underneath will be something catalyzed and you’ll be able to wash off the spray paint without hurting it. Test it in an inconspicuous area with lacquer thinner on a rag. I’ve seen way too many cases of someone using a spray can to “fix” an imperfection that could have easily been buffed out in the first place and making a horrible mess.
