My rear tires are slightly scraping on the rear inner fender lip when going around a corner. The lip is about 1/2"

I have watched videos on the Eastwood fender roller, what are the odds that I will crack my paint. I will have to roll most of the lip. My only other option is to buy new wheels...

Seen entire quarter panels destroyed with one of those on 2 different cars. Front fenders have even less structural resistance to ballooning.

Be very careful.

Is the lip stock or has it already been worked.

if stock, then straightening the inner lip (the one that is on a 45 degree angle) only should provide 0.5" clearance.

You have a better chance of doing damage than not, I wouldn't recommend it.

I’d be inclined to cut the horizontal flange back before bending it. As has been mentioned, there is only a little to be gained on that flange before other parts of the quarter will be the limiting factor on tire fitment. Might have a bit better luck on the front.
There are a few models of car where the shape of the wheel opening and the flange mean that you can gain a good bit of clearance (still with the associated dangers of damaging the paint or distorting the fender or quarter) by rolling the lip. The quarters on a trifive with the way they partially cover the wheel and tire don’t lend themselves to getting much clearance this way

Are you running with an anti-sway bar in back to minimize the tire sway back there? Just a thought, but I would exhaust all avenues to stiffen the ride back there before messing with the sheet metal.

Rear sway bars on a leaf spring car offer little to no lateral stiffnes, the design is to resist roll on the center axis.

I bent my quarter flanges up this way, I would fully expect the paint to crack

New wheels are cheaper than new paint.

I wouldn't risk it with good paint, can you do anything with the rims have a wheel place off set the back space

Heat gun (heat the paint first, that's how the Pro's do it ).

You could always get a Pro around to do it, and the cost is probably not a lot different to purchasing the roller yourself and making a mess of things.
