The roof-rack project taught me how much the order of assembly affects access for a sealant nozzle. Dicor is another roof-sealing material in my purchased kit, alongside the mounting hardware and preparation supplies.

The item in my kit
I bought Dicor White Self-Leveling Lap 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.
Alternative products
Two alternatives to compare
Kohree retains a cartridge-applied RV roof sealant format, while the black butyl repair tape uses a wide adhesive strip; bead placement and strip coverage create different roof-repair layouts.
Kohree White RV Lap Sealant
This white self-leveling sealant is packaged in cartridges for RV roof work. The multi-cartridge set supplies material for applying beads around roof details.
