Have a 1983 Georgie Boy that had tiny pin size holes in spots, the
aluminum is very thin, strong soaps and acid rain can cause.
Our first rig was one of those 21 foot white with yellow stripes, Minnie Winnies. It had the aluminum roof which i thought would be a great idea. NOPE,, it wasn't.
It corroded and had tiny pin holes all over. Back then, the white cool seal stuff helped some but i had to keep an eye on things because leaks would eventually show back up. Hopefully a better product has come along to help with sealing roofs these days..
