You can use aluminum "pop rivets" in place of the missing ones. They will need to be sealed with a product such as: Gluv It, available at www.westmarine.com<br /><br />The other choice is to replace the cold rivets by hammering them into place with a block on the back side. A lot depends on where they are located.
This is a subject I covered awhile back. go to this link: web page <br /><br />This was my bread-an-butter for many years and is the only diffinitive method for repair that last the life of the boat with excellent appearance results.
