I'm doing some layering. I was using jumbolon in place of CCF but I've found, what is possibly the closeset material to a CCF, a replacement for that. So its a Deadener, MLV, CCF and OCF. I've also found the OCF in shoba. Was dirty but I washed it up and combined, these have done wonders.
About the SSHW, availability is an issue. Also I needed a small 12ml bottle from the states, that's why I whatsapped you.
