what is the mix ratio for an eggshell finish using dc 2000 clear with dx 685

Answer
Hi Kevin,

The only flattening agent recommended for DC2000 is SU4985 Universal Flattening Paste. Here is the tech sheet for SU4985

If you decide to use DX685 as a substitute you will need to test it. Again there is no official recommendation for using DX685.
