Reply to "Heat Shrink Tubing"

I had help with motorcycle wiring this Summer.  From a real experienced guy, he used a refillable hot air type cigarette lighter, on 20 ga wire connections.We were inside the dash so space was at  a premium . He varied the temperature  by distance to shrink wrap. I didn’t like using my heat gun even with the smallest nozzle because it was cumbersome and put heat everywhere.I learned a lot that day.
