Or there will be enough hot air to melt more than heat shrink....Just remember to put it back before the wife comes home.
Put it all together and shrink it later when you’re armed and powered. I’ve had to do that a few times when forgetting to bring the gun from home..We all seem to agree that an electric heat gun is the way to go, but what is the best to use if you are on your boat and don't have 120V power?
