Sunroof delete panel sealant

[BKO 5]

Just wondering what sealant people have used when deleting their sunroofs using a metal panel riveted down. Ive done alot of google searching but get a variety of thing used from seam sealer to window sealer.

 

Thanks

Can't go wrong with SikaFlex if you can get your hands on it. It's not for automotive applications, but we use it on wind turbines (which see more vibration over a lifetime than a race car). Wear throw away gloves, it's an industrial caulk.
