I’ve just split a headlamp using heat and now need to clean off the old sealant. Now I’ve seen some shit stuck to blankets in my time (mostly for pleasure) but this stuff takes things to a whole other level.
Fucking witchcraftI've opened and resealed headlights & taillights.
I usually bake in an oven @ 225-250 degrees x approx 12 minutes to soften the butyl, then pull apart.
Pretty sure GooGone is what I used to remove the butyl. Anything stronger would cloud the clear lenses.
Butyl tape or seal a putty like soft rubber in a roll
