We have a BlueROV2 that we already dived and worked well. But now, after some months abandoned, we tried to dive it again, and it started to leak.
At first we thought it was the main junction, through the big O’rings. But after close inspecction, we figured it was through the potting of the penetrator. It seems it is a common issue for what I saw through the forum.
The problem is: here from where we are (Spain), the epoxy resin you recommend for the potting (loctite marine epoxy) is not distributed, so we want to know if there is an alternative we can use.
Also, what is the correct procedure to repair this? do we need to cut the wire and insert it in a new penetrator? or can we put this resin on top of the old one and solve the issue?
