Best Sealing Tape Option

Our travel trailer is now 13 years old and I want to do a complete sealing job using Eternabond. I want to seal the four sides of the roof and the seams around the two slideouts. I am also replacing the slideout seals. I want to get at least another 7 years out of our rv. It is 24ft with two slideouts and it works great for us.

Looking up Eternabond on Amazon I also find the following recommendations. I'm not concerned about cost what truly is the best sealing tape to use that will last?

Here is the list I have found:

Lion Knight, E-SDS, XFasten, SUNLL Butyl Seal, CANOPUS, Amazon Basics Gaffers Tape, WellLuck, Ziolla, CANOPUS

Thanks in advance for your suggestions and comments.
  • What kind of roof do you have? rubber, fiberglass, aluminum?

    The 3M is great tape. Just get the 3M, none of the tape is expensive.
    Don't use Amazon. Ebay has it too and is not funding the hatred of America. Do your homework on where your money goes.
    Tape works great for a quickie fix. Long-term is another story. Eventually you will need to re-do, remove or re-work your fix-it job. The tape makes a mess. If you can do your job with Dicore Lap sealant then use the sealant, NOT THE TAPE!!!
    The tape will leak anywhere there is a small angle or crevice as the tape cannot fill in little gaps, you will have to supplement with lap sealant anyway to fill the gaps the tape leave behind, or water will get in and rot out what you think you are protecting.
    Don't use the tape to waterproof the camper. Do use tape to tape down solar panels so you dont have to drill holes, or to make a patch over a hole on a flat surface. The tape has its place, but not for your purpose.
  • Why experiment? I'd stick with a winner with a proven track record. Eternabond.
