Dale,
I think the proper way to install that panel is with rivets, or bolts, or both. A panel that size may only need rivets. Our riveted coach is a 40-footer, so the 45 might be done differently, but I still doubt the rail would be attached with adhesive alone. Most panels should have some sort of sealer, like what IBP provides or the 3M stuff Paul mentioned.
Are you near I-10? We’ll be passing through on our way to California in our Vogue next Friday, and I’d be happy to stop by, check out the new bus, and take a look at the panel. I have the same rivets and tool Mango used, and they work really well—I can bring them along. If you have time, a picture of the panel would be helpful.
Send me a PM if you’re interested!
