How to "freeze" the Epoxy cure process...

Silica doesn't add strength chopped fiber adds strength silca just aids sanding like micro balloons =plastic

Thats all it does though? It says it increases strength on their product page though. But yea, might be a good idea to throw in some CF fibers.

406 Colloidal Silica is a thickening additive used to control the viscosity of the epoxy and prevent epoxy runoff in vertical and overhead joints. 406 is a very strong filler that creates a smooth mixture, ideal for general bonding and filleting. It is also our most versatile filler. Often used in combination with other fillers, it can be used to improve strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface.

chopped fibers I'm reffering to are "chopped cotton fibers" not carbon fiber but that will work also for some instances. Chopped cotton fibers work best when laminating two pieces together such as servo mounts to hull.

I'm gonna assume you're not actually talking about regular balls of cotton that can be found at any convenience store?

Ah ok, fluid -- would cotton then be stronger than chopped CF cloth in the mix ?

Yes it would for certain applications. Such as described in previous posts. layering chopped fiber when laminating anything it will be stronger.
