Sea Cock advice

[FenderPhil]

Boat is coming out for annual service in a few weeks. One job I need to look at is a sticky seacock. What is the best product to use?

Blakes or does anyone have experience of Lanoshield which is lanolin based and non toxic

TIA

Is it brass/bronze/DZR normal regime is to remove and dismantle for inspection every seven or so years. Its a good move to replace all on a planned seven year basis all fittings attached, skin fitting, valve, bends tails etc.

DZR is a good replacement product don't use brass.
