What sealant do they use to seal tail lights?

[opiateofsorrow]

Hello all! There is a grey type of sealant in my aftermarket tail lights. Do you know what type of sealant this is, or is silicone a safe alternative? Should I scrape the sealant out and use fresh silicone sealant? Suppose its always a good idea. The lights aren't old, so the sealant in there is still quite fresh and so clean.

IMO I used 3M urethane. Same stuff the glass guys install windsheilds with. Try to see if they have a clear. If not then use silicone.

Yea any waterproof silicone will work.

Butyl is the best. you can buy it in a roll and if you need to open the lamps after you seal them, you can heat it and open just like the oem stuff. later.
