Fiberglass Repair


No full service marina in Southeast Wisconsin is as dedicated to fiberglass maintenance like Gage Marine. A seven-bay work shop and paint spray booth are just the beginning. A staff that is committed to just fiberglass work means that, whether you need a new transom to keep that classic running, or just a buff and wax to keep that showroom shine, Gage has the professionals to get the job done.

Do you really need that new boat?

Restored fiberglass boat better than new!Pictured is a customer's 1967 Correct Craft Southwind ski boat. By the mid-90's the boat was showing its age; rather than recommending a new boat, we suggested revitalizing the orginal.





Fiberglass restoration for vintage boatsThe result was this beautiful Awl Grip paint job and a new interior that has the boat looking better than the day it was delivered. When your old boat starts looking its age, don't be too quick to trade it in on the younger model. Instead, give us a call. By the way...these pictures were taken seven years after the restoration!
