OEM Spoiler Trunk Leaking

[NickMav]

My 91 318is trunk spoiler bolts are leaking, what should I use to seal these bolts?

That car should have factory/dealer holes. They have foamy washers. Id suggest remove the spoiler and replace those. Good time to clean the trunk and underside of spoiler as well.

You sure its not something else? Trunk gasket? Tail light gaskets? WindSail grommets?

I removed it cleaned it and put the foamy washers back as well as some silicone. The bolts are M5.80 im thinking about replacing all 6 but theyre a little hard to find the exact bolt shape. I might have used the wrong silicone to? Im positive its the bolts because there are six damp circles on the trunk lining. What are the windsail grommets?
