I'm doing some DIY harley headlights this weekend. The lights are DEPO models and holy SMOKES do they have a lot of silicone holding them together! Probably take most of the day to remove all of it with a lot of trips to the oven to help soften it up...

Check it out (phone pics, sorry for the quality)

Here's just the lens, you can see the black going all around the side:


And here are 2 of the housing itself, the gunk is going all around the channel that the lens sits in, gonna require some serious elbow grease to remove:

 

Use Butyl to reseal.

be careful putting it in the oven so much. it caused my headlights to have spiderweb cracks like crazy

 

Thanks for the heads up - I've been putting it in there on really low heat (150 degrees) for about 5 minutes at a time. It's working, slowly but surely... I'm about 50% done with one of them. The other actually came clean very easy.

 

my old lenses were like that for a while idk why they did it. its was way before i painted em for you

 

150*F is nothing, they get that hot just by using halogen bulbs. You are safe up to 250*. At 280-300 they begin to deform/melt. I use 235*

 

the ones you gave me had cracks and i swapped my stock headlight lenses over and they cracked too. i guess i left it in the oven too long

 

How long do you leave them in the oven 'Raptor' ??? Thanks

 

I use 8-10 minutes at 235

 

^^ Thanks !!! Mine are apart, but with the silicone MESS !
