A word of advice use a heat gun to heat up the paint on the edge or it will crack.

The problem with that is that its hard to get it the same on both sides. I would just buy the tool and learn how to use it well... then just charge people to roll their fenders since it seems that everyone is hopping on the low offset band wagon.
