I forgot I had this tube of Hondabond in my garage. When I found it half of the tube was fine, the rest is rock hard.

I just now see it says to store in a cool/dark place is there anything I can do about the rest of it or is it trash? I don't want to buy another

 

Any tube of sealant you can buy at the auto parts will work the same, you don't need to use Honda bond.

 

Buy a new tube.

 

You should probably buy a new tube if half of it is already cured, since there's no easy way of extracting the uncured portion without cutting the tube in half, at which point you wouldn't be able to reseal the good portion. I personally cannot tell the difference between Hondabond and Permatex Ultra Grey. Both are high-temp RTV(room temperature vulcanization) sealants, and both remain rigid when cured. I use Ultra Grey for most things, and Ultra Black when I need something that remains flexible when cured. I also have a tube of Ultra Copper for exhaust gaskets and the like, but I don't use it very often.

I beg to differ....Hondabond is much better than an "RTV Silicon" you can buy from an auto store.

From my experience it seals better, cleans up easier, and applies better.

same here.

 

The Permatex Ultra Grey stuff is more like Hondabond 4 than Hondabond HT.

Although, I did recently use a Permatex RTV sealant that was speckled black with a starched pasty consistency like Hondabond HT. It's sitting in my tool box if anybody cares to know the market name and maybe part number. I bought it from Autozone.

 

I like Hondabond the best but the Right Stuff by permatex is also a great silicone but is pretty spendy.
