I'm adding a forward remote ~10" antenna for my rear back-up/observation camera to get a better signal to the monitor in the tow vehicle. The coax cable and antenna is light weight and the antenna came with it's own 3M PE tissue tape on the bottom. I'm securing the ~15' of coax with zip tie mounts that also have outdoor 3M PE foam tape. The 3M tape is designed for outdoor use and can handle high temps but I want to add additional support to make sure the antenna and zip tie mounts don't come loose. The zip tie mounts do have small screw holes (not the antenna) but I would rather use an adhesive or silicone to help secure and keep the moisture away from the 3M PE tape.

Would acrylic latex chalk with silicone work or better to go with dicor lap sealant?

Thanks
