Hi Jed,
Keep an eye on mix ratios, ive noticed the 1 to 1 mixes are usually a tiny bit more expensive, but if you dont have scales or wanna bother with tricky mixing, the added cost is definately negligable.
Smoothon does offer an excellent 1:1 mix, i use thier Oomoo 25, it has a faster cure time (4 hours)
Ive also noticed that platinum based silicones run higher than tin based (obviously
ops: ) so watch for that.
if you do have scales & dont mind mixing 12:1 or other ratios, you can find good silicones around..... Quantum Silicones is one that comes to mind.
I hear from professional casters that most silicones are bought & resold from GE (General Electric) who may have some sort of claim to the compound, but for small quantities Smoothons mix is very easy to use & theyve always been prompt with shipment. (for me anyway)
