Seam sealer doesn't really coronate with filler work.I have all the filler work done and now the car is in primer surfacer. A high build sand able primer. I will sand with 150 to get the car straight. Do my seam sealer around the drip rails and a few other areas. Then prime again with primer surfacer. Sand with 320. I feel that using the seam sealer after the first cut of primer surfacer and then re priming over the seam sealer it helps to blend in the edges of the seal sealer. As the seam sealer I use has some sand ability to help blend. Not sure if this will make any sense or not. Just the way I prefer to go about things.
