What did you do to your RV today?

Repaired a crack on the engine coolant overflow tank. This Permatex repair kit seemed to work great. Im curious has anyone ever used this for a gray or black tank repair? I have a tank that leaks when nearly full. I haven't really given it much thought to repair because I dump every 4 days. It hasn't caused much concern.. yet!

It's hard to tell from the pic, but it looks like a fiberglass patch? It should work on the black or gray tanks, but the trick will be getting at the leak so you can apply the patch.
