Bent radiator fins - any good method to straighten out?

Just bought my M2C about 2 weeks ago and I'm in the process of minting out the front end. I'm down to the radiators - obviously they are quite exposed on the F87 so they are susceptible to slight bending. Does anyone have any good methods at straightening them out? I started out by using a long flat head screw driver, but it didn't really work like I waned to get the fins back into position.

I've never used it, but have seen folks recommend Schwaben Cooling Fin Tool for this purpose.

it doesn't look to me that such tool is of any help. I think you should get a better job by carefully sliding in a steel bar of suitable diameter, maybe 1.5 to 2 mm

I used to use a butter knife on the radiator fins of my motorcycle.

Are there any downside of bent fins other than cosmetic?

In theory, it prevents airflow through the back of the radiator to maximize the cooling. In actuality, I suspect the difference is minimal boarding on undetectable unless most of the fins are bent.
