Where did you find this dual setting heat gun? that's what I'd like to have. Right now I just have a Dewalt that has high, medium, and low heat setting. I asked them at Menard and they said they don't make such a thing.
I just went to my local hardware and lumber yard. The place is called Spenard builders supply.
My local AIH (Alaska industrial hardware) also had the same one but for ten dollars more.
These stores are exclusive to Alaska.
Tell your local guy he needs educating on power tools.
They had an adjustable setting Porter Wagoner at my local home depot but I preffered the Dewalt.
I was using an adjustable ryobi and really liked it.
But I broke it and it was my fault.
There are a lot of adjustable temp heat guns out there.
If you look you'll find one.
