Getting spray foam into tight spaces

Hello,
I finally got to the dry-in stage of my shop. It’s been a long road but I’m fairly pleased with the result. It’s a timber frame enclosed with SIPS. I’m getting ready to foam the gaps around the windows and my door. I have a Dow Great Stuff Gun which I like but I may get a can of the Lock-Tite foam as well for the electrical chases in my panels.
Does anyone have any tips for using the cans versus the gun? I know the cans are kind of a mess if you don’t use the entire can so I want to have a strategy once I start spraying. I have had good luck with the gun but the applicator tip doesn’t seem as narrow as the can so I may try cans for the super tight spots.
I built the structure pretty tight so I guess that’s encouraging.
Thanks.

Hi John...
I believe you can just use a piece of flexible tubing like this:
