I have to agree that having the high visibility markings help with making the glider stand out more in comparison to all white. Even if it is a marginal improvement, I'll gladly take it.
I've been looking into adding some high visibility markings for my glider here in the US. I know there's the paint previously mentioned from SH and others, as well as the the 3M foil available online from some online sailplane supply stores in Europe. Any pros/cons to using paint or the stickers (other than the removal or application already mentioned)?
I've tried to find a matching 3M product here in the US as the 3M foil I've seen online in Europe but can't. Anyone found a similar/comparable product in the US? The closest I've found is a 3M Scotchcal highly fluorescent vinyl sticker that seems to be same thickness as is used for contest and registration numbers.
