What is the life of a fiberglass dome?
Our observatory domes are actually fiberglass re-enforced poly-resin with gel-coat finishes. This material id often called “Marine Grade Fiberglass” as it is the “fiberglass’ used to make boats and watercraft. The “published” life of this material is 30 years, but the reality is that with proper care it will serve you indefinitely. If possible, wash the dome with soap and water once or twice a year. A coat of “clear-coat” car wax will also make the dome look “new”.
