The item in my kit
I bought Red Devil Black Acrylic Latex Sealant as part of my camper van equipment.

Where it fits my build
I removed the factory roof covers, widened the mounting holes and scraped the paint and adhesive from the landing-pad areas. I then fitted the landing pads and assembled the side rails, crossbars and fairing.
The sealant timing made the assembly messy. I applied it early and got it on my hands and parts, while the installed pads left little space for reaching underneath with the nozzle.

My build notes
The access around the pad was the memorable part of this job. Small spaces between the roof, pad and rail affected how I could position the sealant and tighten the hardware.
The order of assembly changed which parts of the joint I could reach.
