I could live with the way the looked if the performance was there and didn't affect cruise speeds. Vlad, yours look great.
I?ll look for some debonding agent. It looks like it will still be tough to work in around the VG?s to remove them, but will study it some more. I'll put a stripe of some sorts down the wing where they once were.

I don?t know what the plane did before they were on since I bought the plane like this, but my instructor and I did some testing a few days ago (temperature sixties) with stalls to get some numbers on it. Here are the results we got with about a 1,650 gross weight. Indicated airspeed showed:
60 mph no flaps
55 mph 20 degree flaps
50 mph full flaps
I suppose that is okay, don?t know what others are getting with or without them. Flying solo should be better. For cruising and top speed, others I've read say it's about 0-3 mph slower here. I suspect the latter number is more accurate, but don't really know yet.
It?ll be a spring project, but the day I remove them, I plan on taking it up one more time to get numbers before and after.
