I know that it's low tech, but I have sailed my Hobie for years somewhere where I couldn't leave the mast stepped all the time. My mast is on and off all the time and so I notice bends more than if you left it stepped all season. The procedure that I used is quite simple. If you have two sawhorses and place them at the edges of the bend and the sit or stand on your mast in the spot in the middle, you can get rid of some pretty nasty bends. the process takes time and you may over bend, but I weigh 200lbs and I have stood on my mast and bounced before and not even come close to kinking or folding it. We don't really realise the amount of force wind and water put on our equipment so I am sure that there isn't much damage that you can do.
Ofcourse, I don't have a comp tip, but if I did, I think I might steer clear of it while I was doing this. Keep the sawhorses situated on metal!!!! Good Luck, like most things that we do ourselves, it's trial and error. Beener
