I wasn't anywhere near boiling when the props went in. Black took the longest.View attachment 21644
I noticed you have a P2 in your signature. This would work fine as the hubs are metal (and everyone has tested).
For those with a P3 - I would be doing some test as the hubs are composites and may be affected by heat.
Part of the dying process with Ryt Dye is to boil. Its unknown if the composite hubs will be affected - eg shrinkage or the dye adhering to the hub and changing the texture/friction and ultimately causing slippage and prop-pop-off from the active braking in the P3 esc/motors.
