I recently got a new heat gun that came with a diffuser. I thought it would be a good idea. I assumed that I would measure the 4" distance from the outlet of the diffuser to the wood but that doesn't seem to heat the wood as well. If I measure from where the diffuser attaches to the wood it gets too hot too fast. I realise I'll sort it out eventually but I'm just wondering if others noticed the same thing when they tried a diffuser.
