here is a dumber than dumb question, and I have always felt to dumb to ask without doing any research....... Is the gluvit to protect the metal from corrosion or is that a completely different product?
I have a North River and do have zinc on it but don't know how good it is as I can see little marks forming on the hull. Is that typical and is there a product I can use to remove them? Would a good coat of wax stop the salt water from making those little beauth marks?
the Gluv-it or Coat-it is used mainly on drift boats, on the bottom, to provide something 'slick' for the bottom of the boat. Bare aluminum sticks to rock and these bottom coatings help it to slide over them instead.
Thanks RogueFishr, someone told me of a product to put on the sleds to protect them from the salt water but I don't think it was Gluv-it. Maybe I will go ahead and ask but someone will most likely tell me to search the archives.
For minor pitting, I would sand as best you can, use an acid-etch wash, zinc chromate primer (2-part from Petit), then 2 coats of Easypoxy (1-part from Petit). Brush it on. All available at Fisherman's, GI Joes or W. Marine.
Gluv-it is hell when it starts to crack, which it will. It also doesn't do anything structurally to the point where you can rely on it. If your pitting is really bad, you need new aluminum.
Also, why are you getting pitting in the first place? Is your electrical system grounded to the hull? On an aluminum boat, it shouldn't be. Check for disimilar metals. The only thing in contact with aluminum should be paint, other aluminum, wood, vinyl, plastic or other inert items. Stainless will make aluminum oxide but it's hard to avoid fasters of some time of metal. No copper, bronze or carbon steel.
i would avoid putting gluv-it anywhere on the inside of your boat. it's designed to be slick and that's the last thing you need more of inside a boat. seems like zolotone, bedliner and the like get the nod for inside coatings most of the time. there have been mixed reviews on sharkhide so far.
all that, and i didn't tell you to go search the archives (even though you really should - it's a topic that has come up many times in the past).
