General harness build question on suppliers for harness build materials ie lacing cord connectors & boots, heat shrink, and potting compound etc.

Hi just wondering if you guys have found any decent suppliers for the waxed lacing cord you used on the course. also a general question where are you guys buying the connectors & boots, heat shrink, and potting compound from? i am based in the UK if that makes any diffrence. thanks

IS Motorsport would be a good go-to for you I'd think. You should be able to get stuff out of the US from either milspecwiring.com or https://racespeconline.com/

Hope that helps, cheers.
