Before buying my Newell Classic, I was the proud owner of an Airstream trailer. During this season in my RV life, I learned about Olympic Rivets. Since moving up to the Newell world, I've incorporated this knowledge to replace numerous rivets on my bus. Although they go on like a pop-rivet, if you buy the (rather expensive) shaving tool, as I did, you end up with a rivet head that is truly almost impossible to tell from a "real" rivet. I bought mine from the following link; however, I'm sure you could find these parts elsewhere:

Good luck with your rivet repairs. Most of us have been there.
