seam sealer for rear chrome bumper

[79Scott]

Hey guys,
My 86 has a chrome bumper that is diamond plate along the top (Stepping Surface) and some of the gray "seam sealer" has come out. It appears to be a silicone base sealer to keep water out of the welds. Any idea what its called and where I can source some?

Thanks

There are many brands of seam sealer available. Any auto body store or Online.
Don’t think it’s different for the bumper.
I plan on using gray sealer for the bumper on mine. Whole bed needs re-sealed as well and will likely re-do the exposed cab seams. Easy to do and counter productive to paint over 35 year old seam sealer.
