Looking for help with adhesives on rear lamps
Jeff K Offline
When I got my TC 21 years ago, I took my tail lights apart to clean them out. They were very dusty and dirty inside, but the chrome reflective surface was still in good shape. I carefully glued them back together with RTV Ultra Black. They have been leak tight for the last 21 years.

I scraped all of the old adhesive out of the grooves and am looking for suggestions for something to replace the old adhesive with. I am considering jb weld but I’m not sure if it’s supposed to be a permanent joint. Maybe a caulk would work? Has anyone else had this issue?

I did some research into the various alternatives, chemical compounds, MSDS data sheets, etc., all that good stuff. I concluded the best choice—and what I then used on my left outer tail-light housing to attach the newer outer replacement lens piece—was the caulking you would use to attach/seal sliding metal-framed doors in your shower.

This is it:

This product has a good temperature range, and has minimal shrinkage. And, as anyone who has gone Swimming In A Pool—AFTERWARDS—Shrinkage is a problem, the less the better.

Fixed it a couple of years ago, and even in the desert heat it has held up well.
