My driver side cutout was too close to the pipes and singed the paint - can see it on the trailing edge in the first photo. I used a dremel tool with a sanding drum to enlarge the opening after masking out the desired area. I was surprised at how easy it was and it didn't mar the paint - left a clean edge that I was able to touch up and the modification was undetectable. I would assume the gelcoat is more durable than paint so this method likely won't dull or otherwise damage the finish. If you rough cut the opening you'll have plenty of space to try the finish cut before getting to the edge where it matters. Also, the sanding drums were the perfect diameter to negotiate the curves.
