Drip Rail - Seam Sealer or Body Filler

[BrianG]

I am really having a bad day.

My truck is in the body shop, it has been there for the last several months. It
is getting close to being done. I just found out today that the guy who I've been dealing with, no longer works there. Lots of worry and questions in my head right now. So, one of the guys who is now working on it, is "finishing" up working on the drip rail. He said he decided to use "Plastic" (his words) instead of seam seal because (again in his words) "if the old seam sealer cracked and went bad once, it would probably again". So, I said, I thought you were going to use that auto leveling seam sealer. But of course, I've been dealing with some one different all along, and this all happened without any knowledge to me or any conversations. Anyhow, So, I asked him... By Plastic, do you mean body filler? He said yes, and showed me the 2K stuff. He claimed it will hold up and be better than the seam sealer. Whatever.

So, my question to all of you that would know more than I do (and maybe my new body man) about this subject.... Will "Plastic" or Body filler work in replacement of auto leveling seam sealer for around the drip line about the doors and windshield?

Your help would be greatly appreciated.
