After I took out my rear seat and started cleaning out the floor I noticed a 1/2" to 3/4" gap in the seam that is circled in the first picture. I was able to get it back togther to match the other side. My question is ,it was filled with some black goop that oozed out.Is it supposed to be filled with some kind of sealer or should it be spot welded or just welded together.I could not tell on the other side(last picture) but it didn't look like it had any thing in it.
