I used Blair brand "Holecutters" to cut the 13/16 hole on the fender for an antenna and a 3" to cut th hole above the rear view mirror for the speaker (both placed per accessory manual specifications). After using a center punch to dimple the surface, I was amazed at how precise holes were, with no "walking" and no damage to either painted surface. I wouldn't hesitate to use them to cut holes in another painted or powder coated surface.
