Silicone will not bond the two surfaces and will eventually (after a short length of time ) let water in

The rails can normally be resealed every 5 years with non setting bedding sealant .

I believe our vans (Adria) are sealed with a substance similar to Sikaflex or Tiger seal but you have to be careful with that as a statement because sikaflex make sealant adhesive as well as adhesive sealant two very different products.
If I were sealing an awning rail I would use non setting bedding sealant as on roof lights heater covers, aerials etc or sealant adhesive because the objective is to seal as well as stick and not stick as well as seal.

Very interesting, thanks for this. I have used silicone to repair a leak from around my rooflight. I will look to sort this now.
