I was going thru all the screws that hold down the trim and the skirting on my Grand design 5th wheel. It is just 3 years old, it is amazing how many screws were loose. Well, about a dozen heads of the screws just popped off, leaving the screw still in the hole. Anyone have any tips how to repair them?

I was thinking about putting new screws in beside the old broken ones, and then calk the holes with the broken screws with silicone. Any better ideas than that?
