If you read through that, it is really all the same stuff except muddied by un-associated problems. We tease athomas that his post signature should be his L10 tuning instructions, which are pretty basic and in line with the factory instructions. After about the third time he goes over them, the OP will usually pick it up.
Not that you need to polish the o-rings, but yes fine turtle wax rubbing compound on a smooth rod that is snug fit in the o-ring will take the inside mold line off, which is what breaking it in does. I have a stainless rod that came out of an HP printer. Some of them are not bad to start with. If you can see the line without magnification, it will need breaking in one way or the other.
