| | | 11. While triggering the Gun, examine the atomized catalyst, making certain it is properly entering the spray pattern. | | |
| | | |
| | | NOTE If catalyst pattern is too narrow... ...increase catalyst atomizing air in 5 pressure increments. If catalyst pattern is too wide... ...decrease catalyst atomizing air in 5 pressure increments. | | |

| | | 12. After all pressure adjustments have been completed, a final spray test should be made. Spray a test shop sample on a clean piece of paper. This shot should be approximately five feet in length. You can now check for desired gel time and uniformity of curing. | | |
