Morimoto RetroRubber OEM Grade Butyl Headlight Sealant, Black A330

Best butyl glue you can buy - repeat purchaser

For myself I bought this to reseal my custom painted headlights and for my first time doing it this was a 100% needed purchase it made it so much easier and sealed perfectly no fog with in the headlights

Works great easy to use

I want to tell you just buy it. The rubber seal is very strong and easy to deal with it and become flexible after heating up by heat gun unlike others brand which takes long time to stretch it.After 3 years it's still usable as first day.

Once you get it going you can not stop .

This butyl rubber appears to have a slightly higher temp profile than others. When you go reheat it to do your final press and seal, this stuff is very sticky for sure. It gets soft as intended, but stays together. Other butyl rubber that I've used in the past, becomes sticky but also really messy. This stuff is sticky but not as messy if that makes any sense. You can hear any air pockets come out of the channel, as your squeeze together the lense together, so you know you have a good seal. Clean up is very easy with some alcohol.

This is great stuff! Used this to reseal my headlights after retrofitting projectors. Very easy to stretch by hand to lay in the channels. Once lens is back on, I put them in the oven for 7 min @275F and the butyl tape sealed nicely.I had to reopen them and they came undone easily. Just needed to use a knife to cut the strings; this stuff gets really stringy and can get on your lens. I made a mess at first but it cleans off easily w isopropyl alcohol.Don’t over-do it. I live in Phx and it’s been 105-115F and some extra butyl tape that gushed out is sticking on the body panel (that’s my fault, not the product).I’m Very happy overall

Used this to re-seal the headlights on my Lexus LS460 after retrofitting clear lenses and upgraded high beam projectors. This was the first time I'd ever opened a pair of headlights so I don't have experience with any other butyl glue products to compare this to. That said I found this product effective and easy to use - I found that if you throw the box in the oven for a bit it's that much easier to work with.
