Jerry Schneider Posted September 24, 2002 Share Posted September 24, 2002 Hey Guys, I'm making the hardware for the hidden rudder bellhorns. It says to use zinc chromate on the steel parts, and Alodine on the aluminum stuff. I'm familiar w/Alodine, but are there any special proceedures to get good protection w/zinc chromate? Also, I see it in Wicks, but what type of business could I get it from locally? (I'd kinda like to avoid the hazard charges.) TIA, Jerry Schneider Quote "I run with scissors."

Joe Cygan Posted September 24, 2002 Share Posted September 24, 2002 Jerry, Zink chromate is an older bright yellow type primer which adheres to metallic surfaces pretty well.There are the newer green type primers which are better in my opinion but,I guess that's another discussion.I would recommend,that the surface be free of any dirt and oils and since it is steel,it's fairly easy to scuff up a little without destroying the integrity of the steel.If you are going to spray it on,you will thin it with toluene.Contrary to what a lot of people think,you can brush it on with good success as long as you thin it to brushing consistency with xylene which will give it a better wet-edge retention.

geograham Posted October 12, 2002 Share Posted October 12, 2002 I am fairly certain that I got mine at the West Marine Store, they had spray cans as well. I am not very impressed with the rust protection, little better than cheap primer. I'd use good epoxy primer and paints, also available at the boat stores.

loganm Posted October 28, 2002 Share Posted October 28, 2002 I'm using the two part (A&B) yellow zinc chromate on all metal parts. Stuff sprays on nice and seems to stick well. Will only apply final paint on exterior metal part but none on interior parts only the zinc there. In addition, during final assembly I think it's a good idea to dip the bolts in zinc and assemble wet. That way the holes are coated and seals the bolt in nice too. For application where tubes fit into another like homemade ruder pedals and surface control tubing, I will do the same wet assembly.

Dean Head Posted November 4, 2002 Share Posted November 4, 2002 Where did you get the two part zinc chromate?. Dean Quote Link to comment Share on other sites More sharing options...
