# §63.5880. How do I determine how much neat resin plus is applied to the line and how much neat gel coat plus is applied to the line for continuous lamination/casting operations?


Use the following procedures to determine how much neat resin plus and neat gel coat plus is applied to the line each year.

- (a) **Track formula usage by end product/thickness combinations.**
- (b) **Use in-house records to show usage.** This may be either from automated systems or manual records.
- (c) **Record daily the usage of each formula/end product combination on each line.** This is to be recorded at the end of each run (i.e., when a changeover in formula or product is made) and at the end of each shift.
- (d) Sum the amounts from the daily records to calculate annual usage of each formula/end product combination by line.
