I use the chrome piece with an O-ring that so many have had problems with. It looks good, so I think I'll keep it.

Remove the o-ring. Get a sheet of 120 grit sandpaper and place on a sheet of glass. Rub the gasket surface on sandpaper. That will produce a flat surface that has enough texture to grab ahold of a gasket. Then I use a standard off the shelf gasket, with a slight smear of silicone.

Like anything, torque the bolts evenly and to the proper torque reading.
