Directly from there site ... I just bumped up my project coverage by 9K to reflect the value/materials now in it.
"Restorer and Builder Insurance
Grundy Introduces the Breakthrough Insurance Policy, Protecting Classic Car Restorers and Custom Builder Businesses and Their Customers' Vehicles.
Grundy Worldwide has been contacted, for years, by restorers and builders who are fearful that they may be held liable by the insurers of the owners of the cars on which they are working. To address these concerns, Grundy has now formed an all-risk, direct primary coverage program that protects not only the interest of the restorers and builders, but the interest of the car owners, too.
R&B Policies Include:
Garagekeeper’s Liability
Cars Being Restored
Vehicles Under Construction
Tools and Equipment
Commercial Auto
Agreed Value
Building and Contents
