Hello Wee Vee, thanks for getting in touch. Would happily recommend using Vactan for the water tank without the need for blacking. We did it again last year after a two year gap, and again there were only a couple of small rust spots. Although we don’t, thorough habit, drink the tank water we tested it recently - a friend offered to drink a glass! - and she said it was absolutely fine....and she’s still with us! The crucial thing, especially if you’re Vactanning the tank while in the water, is to make sure the Vactan dries/cures properly before re-filling the tank. We’re talking days here, depending on the weather. The damper the weather the longer you need to wait. One way to test, though it’s a drag, is to start filling the tank with a bit of water. If the Vactan turns milky it hasn’t cured. Just drain and let it dry and cure some more. We used a small electric fan heater to help the process. if it stays black in contact with water it is cured. We’re lucky in that access to our tank is very easy, via a large hatch in the cratch. Others aren’t so fortunate. Hope that helps. Paul on Québec
