n16 owners!! i'm not saying it can happen to you, but it wont hurt to check........ i recently got a flat tyre 1 morning, so d usuall, pull up d sleeves and get ready to take out d spare. upon lifting up the back board cover i was shocked to see the spare, quarter way covered in water. so upon investigating, the water was coming in from the tail light mounts. had to take down the back and seal it off and repaint the spare tyre bay because of RUST!! yes rust. so if u have the black dripping silicone(i think it is) running below your tail lights, caused by nothing else but the trini heat, take a look
