Hi everyone,

I spent the day yesterday grinding rust off the bottom of my doors. I'm putting POR-15 on it today.

I was just wondering what that plasticized bead is and what it's for. I thought it was a weld, but it's definitely plastic. Some of it fell off when I pulled the trim pieces off. Do I need to replace it? Is it critical? Will the lower trim stay on ok without it?

Thanks,

Mark
