Bronze sail track on an aluminum mast

[twhite]

Hi folks,

Shannon and I just bought an Ingrid 38, and we're looking at putting a track up for a storm trysail. The track I have is bronze, I have all the slides with it also. the slides are bronze also. At first I wasn't going to use it because of the corrosion issue, but then I got to thinking that winch bases are also bronze and they go on with an adequate insulator, and don't seem to cause much problems. So, I was thinking about putting it up with a UHMW spacer behind it. But then I was thinking that I should use aluminum strip as a sacrificial element. Or should I just forget the whole thing, and get some stainless strip?

I should mention that the masts are painted aluminum. Probably with awl grip.

Thanks, and best wishes,

Tom
