Resealing the front glass and headlamp

Can I just apply heat to the housing and close it??
Or, do I need to buy some sealant (Butyl Rubberized Caulking) to waterproof??

Thanks

Automotive lighting Butyl Rubberized Caulking is not in trade for normal people. Clear Silicone is the closest.

You can get Butyl Rubberized ribbion for windshield/rear window glass repair at NAPA.

AT work we use Hot melt glue it comes in grey or black.

If I ever had to take a headlamp apart I would stick it in a pan and put it in the oven at 400* until glue is gooey, then separate parts and clean, being very careful not to damage the inside of the lens(it is not hardcoated)

I find that butyl rubber that comes with headlight works fine as long as coverage is good all the way along seam. The trouble is when/if u discover areas along the seam that have little or no butyl rubber (like aftermarked headlamps). I would imagine you would take some pure butyl rubber in a small pan and heat it up, and then apply it to headlamp. Wasting a screw driver while laying it out is probably not worth it - any tool gets full of almost non removable rubber.
It would definatly be an advantage if butyl rubber could be fed into a gun, but I am not sure how that would work considering its extreme stickyness - most likely tool could never be used for anything else.
I would go for no fume butyl rubber, if not it will fume up reflector lenses in headlight and make them foggy. I would suspect windshield butyl rubber to contain a vaporing liquid, so that a creamy consistancy can be had during install. Glass installers usually ask owner to wait 1-2 weeks get full adehiesion.
The question remains.. who has fume free butyl rubber?
