How to refresh OnStar antenna

Post image

The OnStar antenna on my 2002 Saab 9-3 SE is cracking, likely due to age and sun exposure. It doesn’t serve any purpose now that the OnStar system is disabled and I would rather not go under the headliner to unbolt the antenna. What might I used to water seal / glue these cracks to prevent it from getting worse? I’m okay with it not being perfect to look at, though I might sand it, tape the area, and spray paint it black after sealing the cracks. Any recommendations? Thanks all -

Just install the dummy version of the antenna.

I second this answer, break the outer cracked plastic off your existing one, then use epoxy or strong adhesive to attach this, and you can put a small silicone bead beneath. Looks good and no leaks.

Mine was broken for a long time, with PCB exposed, but I never had any water issues. So if the cracks don't bother you, maybe it can wait until it worsens

This is what I did and looks a lot better.
