Conventional heat shrinking is the most effective way to do it.
Cold shrinking hammer, discs, heat/quench, etc, are all minimally effective if that.
Watch out for overshrinking and false stretch, especially on flat panels.
There are many techniques that you won't find in current literature or on the internet.
Old books on traditional metalworking are a good source of info.
In addition to oxy/acetylene, different dollys, hammers, spoons, picks, etc, you'll need to make some slappers, I make them out of old files.
Shrinking on flat or very low crown areas is done "on dolly", high crowns usually no dolly. I normally use a smooth-face flat hammer vs shrinking face. (I very rarely ever use that). Bring the spot, size determined by area being worked, up to at least a good cherry, and VERY quickly (CRITICAL!) hammer it down. It loses color fast and it has to be worked while it has color. At that point it's also very easy to overquench/overshrink, you have to read the metal and understand what it's doing.
Keep at it, and whenever you get frustrated just stop and consider that you're smarter than that chunk of metal, don't let it fool you!
