Just done my first service on my Superslide now it is out of warranty.......all 3 sump plugs had something

like grey silicone or three bond all over them.......I cleaned then up and replaced the O rings as I could not

clean the gery stuff off.......I would have though a new O ring would do or do I need to use a sealer as well...

...PS all previous services were done at the dearlers.

Thanks for getting back....it is good stuff cannot get it off the old O rings.
