I have stopped using silicone on the Bird. I now use 3M #5200 which is a polyurethane based sealant with two different cure rates available. Great for boats where flexibility is desired - as with a Bird. I pulled alot of hardware off my roof and replaced the screws (with some recommended by you guys) and used 5200 on all seams, screws, holes, and mounting flanges.....the elusive leak is gone!!! And I was able to paint over it after several days.
Available on internet and at West Marine
