Sette: PLAINTIFF'S I i EXHIBIT December 27, 1968 You will remember that Beveral sample hags of Spraydon A vere made at South Plainfield some time ago. These samples vere made in an effort to determine the cause of dust vhen applying this product. Due to the seriousness of the problem and after discussions with Carl Setterberg, the plant decided to go ahead vith a Job sheet proposal vhich vould change the method of mixing the ingredients. In the meantime, ve had hoped that the test results of these various samples vould confirm the need for the equipment changes. The plant has nov submitted this Job sheet and ve should have some indication from 6pray on Research that this is the proper action to taka. We note that you have been folloving up on Mr. Kempthome for the results of this test, but apparently ve have not heard from him. The Job sheet vill be held until ve hear from Mr. Kempthome.
