I'm hungry and there's nothing to eat in this damn house. What temperature and duration are you guys doing when you heat up your headlights in the oven? I have a set of Black Beauties I want to restore because the glue that sealed the headlights turned darker after a few years and that is why I took them off. Over the summer I would like to split them open and remove the glue/silicone, and clean it up. Maybe throw some nachos in too.
No the glue is prevalent and is a focal point now that it turned from clear to yellowish brown. It shows right through the clear lens of the headlight and runs all the way around. Its the glue that was used to seal the front to the back of the housing itself. I put them away in the garage because I was just going to order another set but well we all know how easy it is to find a set of Black Beauties now.
They are a Cobra style headlight/corner with a black interior to give a darker smoked appearance without losing any light output like smoked do. They looked really good in person, probably the nicest SN headlights ever My car @ 10 years ago with them.
I tossed mine in the over for 20 minutes at 230° and I had to do that a few times. While you're in there you should toss some projectors in it.
