Step 2: Get latex paint off of skin
Latex paints and primers are sneaky. Sometimes they just rub off like rubber cement, other times they'll stay in your knuckles for a couple of days. Whenever some Lava soap couldn't get all the Lemon Ice or Chesapeake Gray paint off of my hands, baby oil would come to the rescue.
Rub a little onto the part of your body covered in paint using a cotton ball, shop towel, napkin, or anything else you've got on hand that will absorb the baby oil. Rub in concentric circles from the outside in without applying too much pressure. This isn't a scrub, it's more a gentle, localized massage. You can scrub to your heart's content after you've washed it off with some soap and water, once you feel you've made some progress with the oil.
This worked when I dropped a five gallon bucket of paint on myself while on a ladder in a Sears, because five gallons manages to get past the normal problem areas (hands, arms, flecks on the face from rolling out a ceiling) and into some unusual locations that could be sensitive to paint thinner. Presumably the oil degrades the latex to the point that it will flake off. This is why condom + baby oil = one beautiful bundle of joy 9 months later.
