Will Gorilla tape work on the plastic under belly? I have to cut it to access the plumbing and need to know what works for tape

Colo, based on a lot of experience, I have to say that I am disappointed in Gorilla tape in wet applications -- it does not stand up to the elements for very long. If it is applied in a place that is always dry, it is fine.And I have not found any other duct tape type product that really stays put in wet places. So I will be reading this thread with great interest -- maybe there is a solution that I have overlooked!

So I will be reading this thread with great interest -- maybe there is a solution that I have overlooked!I've had the same experience using Gorilla tape in this application.There are exterior grade Duct tape's that are for use on roof top HVAC systems that might work. I costs more and is a thick, tar-like tape that is super sticky.I bought it at Home Depot once by accident. There's also a 6" wide tape for sealing around new windows during installation. I used it to seal the exposed back side of the tail lights in our TT and it's holding up fine.

There is a woven tape made for this application. I don't know the name but any RV dealer should be able to tell you what it is. I used it on my last rv with great results.Doug

If you want something that will last forever under any conditions, get a roll of High Temperature Flue Tape. It's the silver colored tape that is used on aluminum vents for furnaces and gas water heaters. The stuff so so strong, it will never give, under any conditions. Caution... you have only 1 chance to stick it on and it cannot be redone. So get it right the first time. Extremely strong stuff and extremely resilient to all kinds of weather conditions.

This is what you want. It sticks perfect on the underbelly.

The OP is talking about the black woven tarp like moisture barrier that is used to cover the entire under belly of most 3 season trailers.

Eternabond or Flex Seal tape both work exceptionally well on coroplast.

I have had limited to decent results with the gorilla.

However the only way to get a good stick is clean the underbelly area good with something like alcohol or lacquer thinner. Put the tape on and then follow up with the DW's hair drier for the final stick.

If you mean the tape for designed for use on rodent barrier, it's terrible. It will fall off in short order and doesn't stick worth a krap. Companies that do that kind of work use patches made of the rodent barrier and stick it down with 3M aerosol adhesive.
Sorry but the tape is useless.
