Cone Repair

The repair was made using Gorilla Clear Repair Tape and Gorilla Super Glue. I cleaned the cone around the crack and in inside the crack as best I could with Isopropyl Alcohol. This is a critical step in producing good results, IMO.

I spread the crack apart as much as reasonably possible and dabbed the Super Glue in the crack. A little goes a long way. The crack wanted to spread and it took a fair amount of pressure to keep closed. I held it closed with my fingers for about a minute then put a few pieces of the tape in strategic places to help hold it closed while the glue further set.

Once the glue was set, I used Super Glue and baking soda to make a patch at the inside bottom of the crack. This is a tricky maneuver! Not so easy to make it look like a nice finished repair but it's on the inside so who cares? I spread the glue in a sort of puddle over the crack then sprinkled some baking soda on it. It set almost instantly. I repeated a second time to build up the patch. It sets rock hard.

I then used several pieces of tape on the inside of the cone across the crack and along the length of the crack. The adhesive on this tape is pretty aggressive and the tape itself is thicker than regular packing tape. I chose not to use tape on the outside as it is shiny and does reflect some light. I wanted the repair as unobtrusive as possible.

I put some more Super Glue along the crack at the very bottom of the crack on the outside, from the ground up about an inch to give it some extra strength. I also ran some up the crack and wiped it into the crack to give it a good seal.

 In the photo below, you can see the crack but not the repair. From 10 feet, it's all but invisible. 

Now we'll see how long it holds up!
