Place both resins, china wood oil, and five gallons of bodied linseed oil inn the kettle and run to 545-550'F. Hold at this point for approximately 30-45 minutes (depending onn size of batch and desired final viscosity). Then check with remaining five gallons of bodied linseed oil and thin. Finally add driers. NOTE: This vehicle contains 45% solids and has about a "C" Gardner-Holdt viscosity which is suggested for roller-coat application. Driers are approximate and may have to be increased. It might also be found necessary to use a small amount of iron naphthenate for right dryness and hardness of film.
