I was at a friend's auto shop today and he suggested using a smoker to find air leaks.  He's used it in other applications at his shop to great success.  Has anyone tried this?
Is there a downside to trying it?

On the air system, or to detect air leakage inside the coach?

On the air system to detect leaks.

I like the tried and true soapy bubbles for initial detection, then breaking the system down to smaller sections and testing with a gauge for losses. It's probably safe to use smoke, but is it? Introducing anything but dry air, smoke maybe dry enough, could be a concern.

I'm just thinking if there really is not downside it would potentially make things sooo much easier. But surely I am not the first one to think of this...which is why I ask the question. :-)

David, I think what you will find is that any smoke introduced is going to settle out of the aerosol long before it makes it through a leak that you can’t find with soap.

I had the bright idea once of pumping the air system up with R-134 and using my refrigerant leak detector to sniff around. Didn’t work at all.

OK thanks...I knew I couldn't have been the only one thinking along these lines.
