I installed my Seibon Carbon Fiber SP style spoiler a month or so ago, and the fitment seems perfect. But it seem that when I use the rear wiper, the tip end of the wiper sometimes catches on the spoiler. How can I remedy this? I catches right near where the wing touches the top of the rear window where the glass meets the steel, and only in the top most upright posistion of the wiper arm. Can I get a slightly smaller wiper blade, or cut the tip off and cap it with a rubber nipple or something? Or should I try taking the wing off and adding some washers as a spacer. It only catches like 75 percent of the time, then the rest of the time it scratches against the underside of the wing. And with the snow coming up, I'm gonna need my wiper and I don't want anymore scratching to occur to my wing. You could only see it though if you take the wing off.

 

you can either find a spoon wiper or cut the tip. Of course the fastest and easiest is cutting the tip.
