bent rim lip

I am in the process of painting some steel rims that I picked up, and noticed one of them had a slight bend in the outside lip of the rim.
How should I go about bending that back.??
Some heat and a hammer??
How should I check the straightness or warpness of the other rims, to make sure they are good??
I did roll them on a flat surface, and they seem to roll fine.
Thanks

Minor bends on steel rims can be straightened with a hammer, don't use heat though. Check carefully for any signs of cracking after, especially at the ends of where it was bent. Wear ear protection too, it will ring pretty good.

 

Yeah giver a tap tap taperoo.

 

that is what it looks like after a couple of minutes of hitting...should that be fine??

 

That's nothing, on my old car. Hit a pothole, not once did it ever leak air and no vibrations believe it or not lol.

 

Yeah it looks brand new now

 

This is what one of the wheels on my neighbors jeep looks like lol. Yours looks like nothing ever happened compared to that.

 

I would be comfortable driving with that.

 

Here's my neighbor's rim on his Jeep. Makes yours look like it just rolled out of the factory lol.
