Aluminum protective coating

A Leaky-Dome Nightmare: I am director of a private alternative school. In the 1970s, when domes were the rage, the staff built a medium-sized dome on the property and covered it with thin aluminum sheets. It is now leaking like crazy! We are interested in applying some sort of protective coating to the aluminum to preserve the structure - but do not know where to begin.

Any suggestions?

Dear Carrie,

I hope that is a geodesic dome inspired by Bucky Fuller (one of my favorites). If it's leaking you might try a caulking compound. As far as the surface of the aluminum, you should be able to find some decent metal polish at a hardware store. There are also wipe-on sealers for aluminum available on the market, otherwise try an exterior grade clear coating.

Good luck,
