Need your opinions on mounting kayak to mustang (2007)

[FISH11]

Using any foam or air pads that sit on the roof are going to be a big risk of scratching or scuffing the paint finish due to dust, dirt or sand getting between the pad and the paint. The better option is to get a rack that mount to the body at door openings or gutters. Also the pads might put pressure on the roof that could dent in the center area of the roof. Body or paint damage would lower the value of the car or cost more to repair than buying a rack that can better support the weight.
