Picked up two rolls of 13G wire, 50' of white and black to begin rewiring my boat. Most of it is hidden underneath but a few runs will be visible and I was wondering if there is a wrap other then electrical tape so that at least the dbl wires will all look uniform and match. I searched wire wraps but I may not be typing the right thing. Plus it would be nice to conceal the wire nuts. Thoughts or suggestions alway appreciated!
