My usual vendor for hardware, McMaster-Carr, doesn't seem to have what
I'm looking for.

I need to replace the seal between the upper and lower clamshells of my
little utility trailer. The upper clamshell, hinged at the front, flips
open. When closed, it fits over the lower "bathtub" portion of the
trailer, with enough overhang to keep water out. The upper and lower are
made of fiberglass, about 1/8'' thick.

The upper edge of the bathtub is protected by a flexible channel
weatherstrip. I'm trying to find new channel. The cross-section of the
channel is shaped like the letter "U" (it is flipped over to install on
the edge of the bathtub). It bends, and wraps around the whole top of
the bathtub.

The outside dims of the "U" are: 5/8'' tall, less than 1/2'' wide.

The slot in the "U" is about 1/8'' wide, to accept the edge of the
bathtub, and maybe 1/2'' deep.

It appears to be textured white vinyl over a springy steel inner. A
serious long shot finding anything like this, I know, but the
resourcefulness of the folks on this list continues to amaze me.
