IPA is just the detailers term for the alcohol/water I told you about yesterday. It stands for isopropyl alcohol, it's put in a spray bottle usually a 25% alcohol/75% water mix. I told you for your front To mix it 50-50. But for normal detailing/ cleaning it's 25/75.
Where do you normally use it? Usually after polishing, to get the surface virgin clean to set up for the sealant/coating/wax.
See me use it here:
