Butyl Rubber

Hey Y'all, has anyone used the home Depot butyl Rubber for sealing headlights. $4.50 is a lot better than $20 for the morimoto butyl that looks identical. Link to the Home Depot below:

I read the ingredients and if it is the same, I buy the cheaper stuff.

 

Is this the same stuff people use to seal the front part of the bed corners after they put a camper top on?

 

yeah its a construction sealant for roofs, windows, etc.
my thought is butyl tape is butyl tape. I doubt morimoto took the time to develop a whole new "automotive" grade of butyl

 

Just a name, I bought a no name brand from a local store and haven’t had any issues.

 

So an update about 2 months later. Used the home Depot Butyl and during application it was soft enough at room temperature for everything to fit together without the oven at all. Just used some small clamps to slowly ease the clear shell in place and screwed it together. After that I took some very thin beads and made a full edge seal with my fingers. We have had a bit of heavy rain and such with no condensation. So far so good, will have to see how it deals with 110 during the summers here.
