Most DIYers will have difficulty trying to use spray foam over head on the rim joist. If you look carefully at this video you will see they used what I recommend, unfaced batt insulation shoved up againist the rim. I cut a 2' length of R19 batt and fold it over in half, friction is usually all that's needed to hold it in place.
