There are a few ways to straighten your i-fins. The best method is shown in our video linked below : https://vimeo.com/780713244/13c3922999
Below are also some instructions, but you can also do this with a hairdryer, or leaving it out in the sun on a hot day and it does just the same.
1) Boil a kettle and leave it for about 5 minutes
2) Fill one mixing bowl with the boiled water and another with cold water
3) Submerge the bent fin in the hot water bowl and leave it for a minute or so
4) Remove it and then correct the bend in the fin with your hands (be careful if the water is still hot)
5) Plunge the fin in the cold water to set it back in position
6) Repeat if necessary
