Clay the car ASAP. I'd even suggest doing the whole car. When paint is airborne from an aerosol can it drifts everywhere. Not knowing what type of paint was used in the garage its hard to say if it will etch your clear coat when it is removed but there's no point in waiting. Hit the areas where you did see paint with a light swirl remover (speed not pressure) like Poorboys SSR1 or Meguiar's ScratchX.


Personally, I'd strip all the wax off using your Zaino polish after washing with a liquid detergent like Dawn or a proper auto shampoo.
Try spraying a quick detailing lubricant (Z8?) or whatever you can get at the auto store on the panel before you apply the polish/wax/sealant, let it haze over and respray the panel to remove it. Rubbing on paint is very invasive and considering you should only be doing this a few times a year (polishing/sealing) its very good insurance to ward off streaking the clear coat with dry rubbing. And use the cleanest/newest towels you have. Speed when wiping the surface, as little pressure as possible.
