Ok, so after talking to a few who mix up their own head cement here are a some home made recipes for anyone who is interested.
Head Cement: 1. Sally Hansen's Hard as Nails mixed 50/50 with Acetone or other thinner
2. Regular Lacquer thinned
Flexament: Mix goop with toulene or MEK depending on what the ingredient is in the rubber adhesive. Give you the ability ability to control the viscosity.
I wanted to research homemade options because I teach some new tyers and they are going through the cement and I like buying/tying in bulk.
Give me a shout if you have a homemade recipe that works for you.
thanks,
