Despite everything we figured out, that as soon as the left the nosecone alone for a couple minutes, the ablative would begin to droop, regardless of the method we used to apply it. This is clearly bad, so we have some ideas to address it:
- Using a faster drying epoxy as the base of the ablative, and drying it with a hair dryer
- Applying the ablative in thin coats
- Using thicker ablative i.e. adding silicate or whatever thickener won't ruin the ablative properties
