The info on this page is about painting Coach Yard flexible 'Full Width Diaphragms' and kit bashing the CY FWD to replace the flexible material with latex, which can be painted more permanently.
*****************
Important note: The Monster Maker latex paint must be allowed to dry out some and thicken before applying with a brush. Depending on temp and humidity, a 6ml pool of MM paint in an open glass jar takes 24-60 hrs to shrink to 4ml and thicken enough to use. Brushing on top of many partially cured layers with the thin watery latex paint will end up with the FWD latex curtain cracking and splitting, in time.
