The watery headlights is supposed to be mainly a 97-98 problem <bad OEM sealant>, but can probably hit any car.
I pulled the Drive side off the '98, and it was so trashy inside I tried to pry the clear part from the silvered black plastic. No go, until I filled the damn thing up with water and traced the dribble. Go figure. It was leaking right where a tear duct would be, if the thing was an eyeball, looking from the front, the left most point, at the seam. I also found out that when I carefully pried with a small screwdriver where it was leaking, the weak sealant allowed the 2 parts to almost easily begin to separate. The clear half is grooved into the base at an angle, not "straight in" as I assumed it would be, so starting on the sharp corner and working around top and bottom towards the marker side, is physically the best way to pry em apart.
The shell had been leaking for so long, there was dirt residue inside, which is why I wanted to get it apart. A little dish soap and water inside both sides, and it was good as new, inside anyway...
Scraping the old sealant off is a pain in the azz. I used Clear silicone to rejoin them, after they air dried a bit. I need to refinish the outside again with finer sandpaper, and more patience.
I saw somewhere, prolly on uboob, a guy doing a headlight refinish. He started at 600 grit paper then in stages to 2000. I saw the one point he made repeatedly was that after each stage of sanding the entire surface should appear uniformly hazy. He then hit em with Clear, then polishing compound. They really did look excellent. I might take a step further, spray clear, then wet-sand at 2000, mineral spirits, then another clearcoat. Then polish.
I might worry about it, after the
TRANSMISSION is back in the car
