I have been working on my tractor for a long time trying to fix a short and improve the ability to have lights on the rear of the tractor. When considering options, this appeared to be the best short and long term material to use. I couldn't predetermine the length needed for this situation, so I had to have wire on a spool. I have used the wire for many outdoor situations and am confident that it will serve many years without issue. The wire and coating material is very uniform.
