I agree your gap is more than most, but when they are installed the Hysol fills the gap and can be radiused out with your finger so it looks much better after final paint.

I believe I also remodeled the leading edge bend on the weights slightly for a better fit. You can't do much but you can do some. Also pull them in tightly when you rivet them on-it slightly squeezes the thin flaperon for a better fit.
