Trailer repair tape

I’ve looked everywhere but can’t seem to find any like my company uses. They buy it from the manufacturer in large quantities but can’t give it out. It’s aluminum foil backed but the sticky part is some sort of thick 1/16th inch of black rubber. Can anyone help me out on where to buy it? Or something similar?

 

No but a lot of these trailers have rust holes/gaps near the door and I’m trying to save myself some time. I figure if it’s legal for the company to use it to patch a 4inch gash I can use it on smaller stuff

This trailer has cracks up front and I have a dog food load. The shop that replaced the tire used it to seal crack. If I had been picking up a trailer away from a terminal I’d have to wait for a shop to fix it. If I have the tape I can do it myself right then and there.

 

I understand lol I was just explaining my intentions. After setting for several days my faith in road service is almost non existent.
