While I did a ton of shrinking using an acetylene torch I never did it using a propane torch as noted above. It may work OK but be careful of putting too much heat into the panel. If the spot doesn't turn cherry red in two-three seconds you'll need a hotter torch. I know that sounds funny but you want to get the spot you're shrinking hot quickly so you can shrink & quench it quickly so that the heat doesn't have time to migrate to the rest of the panel.
Excellent point Tiny!
Eric, this might be the time you start looking into a shrinking disc. If you have more metal work to do the disc will pay for itself the first time you use it.
One of the best metal shapers in the USA has his disc mounted on a 20 dollar harbor freight grinder.
So for 60 bucks you can have a tool IMO is idiot proof, has a small learning curve and will work far superior to a torch...Eric
