Default Why do SSE/SSEI tails delam? What can be done to prevent?

I am getting SSEi Tails for my 95 SLE and I am wondering what I can do to prevent delam since the set I am getting is mint. I am thinking PlastX from Meguiars to stop uv-rays from hitting the lenses cause that'* the purpose of the product, and I hear also moisture gets in? What about sealing the edges with a thin coat of silicone? What other ideas are there? Will any of this help me?

Well, part of it is, or was in my case and I suspect in many because of where a lot of delam starts, is the corner of the trunk lid hits the lense edge when shut hard, causing a crack to begin.

I've adjusted my outer tails down so I know the trunk lid won't hit them.

i think differently

its not from the trunk hitting the tails, its from when the Water drips off of the trunk Lid it drops right onto the Tail light. The water then seeps down between the clear lense, and the black lines

also the Expansion and contraction of the plastic cause the black to separate from the clear, as the black insert is "melted" to the clear when they are assembled

when i put on my SSEi tails, i ran a bead of RTV around the entire lenses to prevent the moisture from getting in....so far so good....although i havent seen teh car in about 3 months....

Mine showed clear signs of impact. The delam spread from there. In the last year before I replaced it, it spread very quickly and I finally saw water in the lense.

RTV....very good idea! I might just do that....where exactly did you run it, like can you show a picture or be descriptive? Maybe some of the other members can do this too as a preventative measure....

sun, heat, moisture, cold, bumping, any number of things can cause it.
even 2000 + can get them.

I don't really think you can really avoid it.

if I had to pick one thing to avoid. when a light is out. Don't bang on the lens to see if it will go back on.

Around the edge of the outler lense. It would help in either case of original cause.

PlastiX will not prevent UV damage. It'* merely a very light polish designed to smooth out plastic in lights and what not.It'll smooth out imperfections, and take of a thin layer of UV damaged plastic on the surface you're polishing.
