6.	Patch with durable seams that are as invisible as possible. Complywith tolerances.

7.	Where feasible, inspect and test patched areas to demonstrate integrityof the installation.

8.	Restore exposed finishes of patched areas and extend finish restoration into retained adjoining construction to break of plane in a manner that will eliminate evidence of patching and refinishing.

9.	Where patching occurs in a smooth painted surface, extend final paint coat over entire unbroken surface containing patch, after patched area has received prime and base coat.
