Water Ingress Focus 3 Help part2

[Rayfocus]

I know this has prob been posted before but I'm pulling hair out. Water ingress in the boot issue. I've had bumper off drained quarter panels,  taken  off, cleaned and siliconed the vent seals( plenty of sealant), even siliconed the small grommets where light clusters pop into( locators), still getting a small amount of water on the right hand side of boot. Seems to be damp above this area on the curvature where wiring runs along.  Any ideas ? Please 

Cheers

Mine leaked from the body panel joints next to the tail gate hinges as the ***** Ford mastic dries and cracks causing ingress. I used epoxy resin to reseal them, no issues sinse. Hope this helps
