Chain stay protection

[AngryScientist]

It's a good question.

I know I have purchased used bikes in the past that have had a clear CS protector applied, and by the time the bike came to me it was a hard yellowish mess that was hard to remove and probably did more damage to the paint to remove than if it wasnt there in the first place.

I would want to choose something very high quality that wasnt going to turn into a mess after a year or 5.
