How to Separate Headlight and Fog light lenses (without home oven)

Hey guys,

So I have been thinking about doing some projector lens retrofitting on my trucks fog lights (or headlights) so I made a video no how to separate the lenses. The headlights are sealed beams 6x7 which are common on older jeeps and pickups, but the fog lights are from my B3000. The fog lights came off a lot easier and I am gonna try the trucks headlights next.

Let me know what you think!
