Default Baking headlights for retro

So got headlights out, stripped them of accessories... turned on oven to 250 then turned it off, put headlights in for 10minutes.

Took them out and started to seperate but the glue is like bubble gum and stretching ..... I was told it would split real easy. Do I need to bake them more? less? or is this just the way it is?


thanks in advance!

Dont bake it more. When its stretching just cut it so it doesn't land on your bezel which will be hard to get off.

hmm.... a guy at the retrofit source said toyotas are great as they just seperate the easiest, and I can just reuse the sticky stuff (and not get new/more) because it will seperate so cleanly.....but this is so messy it seems i cant reuse

its pretty messy and hard to take off, just take your time.

a ballpark time should be 250 degrees for 10 minutes and try keep the glue from stretching

Matt is a great guy from TRS. But thats not correct, I doubt any "glue" will separate instantly. When I got my stuff through them, he asked me if I had any type of sealant. I said no, and he recommended me to pick up his butyl. I did at least like 6 pairs of headlights and still have plenty left over.

So just pry away not worrying about the mess ( other then keeping offt the lens and reflector), clean it up after and use new glue later?
if so whats good to clean it up with?

Just keep it as clean as you can try not to get the glue all over the place. You can throw it in the oven to soften the glue again since it'll cool down before you can clean the headlight.

Or just use a heatgun and a old screwdrive/flathead and just clean it out and place new glue.

Pry open and use a flat head to wedge it as u go. I found it easier to control the glue when it starts to cool instand of when its like melting cheese. Take ur time pry bake pry bake pry bake. Ur only tossing it back in to back for a couple minutes each time for the glue.

Some swear by the heat gun but i didnt care for it.

i've done a few retros and i find that a heat gun works best, it's a lot more controlled and reduces the risk of having the glue land on the shroud as you can let it cool down a little after prying it little by little

When the glue stretches you can hit it with a heatgun for a second and it'll go back, just make sure to keep it off the chrome bezel as you won't be able to get it off cleanly.
