I just have a couple question about rivets on these units. I have a Trillium
1300 that the drip cap needs replacing. I am wondering what you guys do with the old rivets that are drilled out, do you pull back the ensolite and pull the inside half of the rivet out or leave it in there? Same thing with the rivets for the roof vent... do you guys drill it out, then push the old rivet into the ensolite or pull the ensolite back and take it out? I don't want to do too much damage to it if I don't have to. Also do you fill the rivet with some kind of sealant?
