I went down to the white van, which had red paint from the wing scraped along the roof edge; so the impact was enough for that at least.
The Rans S6 ESD wing skins are dacron "socks" and colour is dyed into the fabric at manufacture, so the red paint could not have come off "the wing". The cosmetic (and non-structural) fiberglass wing-tips added to later models are painted, so this must be where the red paint came from.
The Rans can be flown safely with one of these wing-tips damaged or missing. I know because I have seen it done. Not in the UK, of course.
