Small amounts of Japan Drier can be added to TotalBoat Wet Edge topside paint for the build coats. If it is used for the final coat of paint, there is a chance that the gloss level of the finish may be reduced, when compared to applying Wet Edge without Japan Drier.
It is strongly recommended to always perform a test sample, not on the final project, to see if adding Japan Drier achieves the desired results.
