2017 Classic - crack developed on rear skylight corner.? I tried Capt Tolleys with no success.? It has very little viscosity and and seeped into crack as advertised.? I let dry and repeated application as directed perhaps 3 or 4 times but it never stopped the leak - it did minimize it though.? I ended up putting Eternabond tape on corner and problem solved.? This was over 2 years ago and 18k miles.? Perhaps not the most aesthetically pretty remedy but it work and that is my bottom line.? I ended up putting the tape on the top corners of all the skylights as a preventative measure?
