    Default Cowl Vents

    Hello All: I've stripped the paint off my cowl vents, and am wondering about next steps. To paint, or not to paint? Can anyone identify the metals here? Looks like aluminum over copper? All I know for sure is that it is non-ferrous.

    I'd more likely guess zinc or tin over copper or brass. Someone else might have a better idea and have better eyes than mine As far as finish, kinda depends on that you're looking for, but it looks like you're through to the base metal in a few places, so I'd definitely re-coat somehow. You might be able to get them re-dipped if you want the metallic finish.

    I painted my aluminum mast on my bristol 30 in 2009 with interlux metal primer and brightside and it still looks great today.

    Not copper, probably brass. If they are old enough they might be nickel plated, if not probably tinned, but I suspect nickel.
    It really is quite difficult to build an ugly wooden boat.

    My money is on chrome on brass or more likely bronze. Very typical mid 1900's Perko or W.C. vents. Yes, send them out for re-chroming.

    Thanks everyone. What's the over/under ($$) on re-chroming all 6, each of which is about 16" tall?

    Re-chroming a bow light for a runabout cost me ~$300 from a local guy. My guess is you would be in the same ballpark for each cowl. It may be a bit less however because I think a lot of the cost is the labor and the cowls are simple to polish.

    I do not see the peeling sometimes associated with chrome, going with nickle plate. Try buffing.

    While I would agree with the lack of peeling being curious for chrome, the hardware on my boat (1957) is not peeling where the chrome is going.

    I vote for chrome on brass and it looks like someone sanded it for paint. Someone on the Cheoy Lee owners site could say for sure. What size Cheoy Lee and is it all wood or glass?
