If you do a search on the GitHub for Prusa slicer or even the Prusa forum you will see lots about single perimeter plane wings. Most of the models are not valid constructs in terms of slicing and the s3d ones use some specific tricks of the slice engine to work.
it’s gotten quite heated at times on the Prusa GitHub thread. I suggest you read through it to get a background to this issue.

I’ll try and find the direct link when Im back at my pc. Searching for stuff on a phone sucks.
found one of them prusa3d#3062

the way the part is made: having a little void inside of it and using "overlapping perimeters" => impossible to fix.

But if you use a 0.3 nozzle with a 0.35 external perimeter width, you should be able remove the defects.
