    another way!

    Hi

    For what it's worth !

    Blast the hull to SA 2.5....Paint the entire boat with Zinga and then apply any topcoat you wish...Your hull will never rust and recharging the zinga every few years is a piece of cake....check out Zinga (belgium) on google...no antifoul required and the stuff is inert....you can eat it they say!

    Good luck...Paul

    Steel can rust and protecting it is extremely important. Zinc is commonly applied to steel to prevent it's corrosion by rust. This is done by hot dip galvanizing and /or zinc spraying. This process requires that you send the part out to a specialty shop. Further, hot dip galvanizing creates a zinc-iron alloy which is brittle.

    How would you like a liquid that could be sprayed, brushed or dipped like a paint and have it protect like a galvanized zinc coating? In fact, how would you like a special formula that has been used widely throughout Europe for the last 26 years and which the U. S. Army has successfully tested on trucks in Hawaii.

    ZINGA is such a formula. Applied wet, this remarkable coating system dries to over 96% pure zinc and is scratch and corrosion resistant. Imagine, you can spray, brush or dip Zinga on your steel structures, welds, fencing, towers, cables and it will protect for years against:

    Don't put any zinc or aluminium based primers below the waterline. just epoxy and antifoul. Inside Zinc it with any tough zinc rich primer then epoxy. Same for topsides and deck.

    Is the hull perfectly formed? Maybe you should add a faring step before painting.

    Shotblast to Spec SA2.5. Immediately cover with epoxy primer. Use the same complete epoxy paint system (make, manifacture) for overcoats. Follows the manufacturers notes and overcoat times religiously. Spray complete hull, above and below waterline, then apply antifouling.

    Use coal tar epoxy on the inside of hull, apply thick - 140+ microns.

    Use an airless spray outfit if possible.

    Remember your sacraficial anodes on steel hull to combat electrolysis.
