Gap Seals

Has anyone installed Flap Gap and Aileron Gap seals? If so, did they help improve climb?

Hi, I've installed a set on a Cessna 182 but not on a Piper. I've considered putting a set on my Comanche but haven't gotten to it yet. From what I hear they do improve aileron effectiveness at the lower end of the speed spectrum, and they are supposed to improve climb rates.
Sorry I can't give you any hard numbers.

Yes I have. Both upper and lower on my 140.
