I don't know, never tried it, When I find something that works well I stick with it. In a saltwater boat if it can corrode, it will. Never had any problems with the heat shrink connectors as they seal both sides of the connection. You'll notice in the picture the small bead of sealant that squeezes out of the end of the connector.
Hi Konabud,
What in the amps on your circuit breaker? I like your neat wiring job.
