I have a broken Aquabot pool cleaner. The pump motor does not spin anymore. Thru some google searches people have found out the capacitors which start the motor blow out. After opening mine this is the problem. Ordered the correct capacitors and waiting on them now. My problem is the capacitors were encased in some form of hard epoxy for two reasons I assume. Since this motor will be submerged in the pool water it needs to be sealed and cooled. Where the wires enter the motor the epoxy sealed the case from water. Then the capacitors were sealed in the epoxy, most likely a potting compound which is thermally conductive. Next the motor is filled with oil to cool and lubricate it. I was told it is 30w non-detergent just like air compressor oil. So the epoxy kept the capacitors from being exposed to the oil. My question is "what can I use to encase the new capacitors I install? What ever is used I don't want it to be so permanent it can not be removed from the plastic case if the capacitors blow again. The old stuff was not very flexible it was breaking apart as I pulled it out. Here are some pictures of some things around the house. Let me know if any of these would be acceptable and work.
