Morimoto RetroRubber OEM Grade Butyl Headlight Sealant, Black A330

Works great easy to use

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.

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.

The butyl worked great and sealed my headlight up just like oem. No moisture or issues!

I coated my inner door panel and outer door (from the inside) with this material. It goes on easy, cuts easily and there are so much more than I needed for my 4 door Jeep grand cherokee. I will buy this again and again if I need more. Its cheaper that big name brands and works just as good. No smell, just as sticky, and nice neat packaging.Get the Rollers!!! Some places inside the door needed a firm hand or knuckles but majority of it was applied better and easier with the rollers.

Once you get it going you can not stop .

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

It fit on good, you have to stretch it or when you try to put it in, and squash your lens together, a lot of extra butyl will spill out (which is good, since it’s a sign of a good seal). People who say they have a leak either didn’t clean out the fitting correctly from the old butyl or overstretched it and made it too thin. I was able to seal my headlights twice with the single roll, I still have a bit of butyl to do one headlights but let’s say if you stretched it, you could possible do 3 sets of headlights.
