I wouldn't risk seed on barricade, it will stop seed germination, and if you aerate, it will nullify the preemergent and allow crabgrass competition. If you are going to seed in the early spring, it should be well planned, and executed at the proper time. Save yourself the aggravation, and go with a fall seeding, now.
