    This is the ESC just out of the box:

    This stuff need some temperature to polymerize. . . At least 30°C and also it has a very low viscosity and don't stay were I put it.
    So I've experimented to thicken the resin with these microballoons: http://www.offshoreelectrics.com/search.php

    I used "plastic dip" Works great and is easy to remove if necessary.

    Looks great though! Good job.
