I need to cap some built up ACQ lumber posts with aluminum, any suggestions on what to use between the two to prevent the lumber from eating away the aluminum? I thought about using felt, or one of Graces products, just wondering if anybody had any other solutions.

Best would be to cap with copper. But more $$$$
I have used Grace I&W as an isolation membrane - so far so good.

Thanks Jim. Copper and cedar are for the next house, at least that is my plan.
I forgot to mention the nails if used to secure the aluminum - SS is probably best choice.
JimNever underestimate the value of a sharp pencil or good light.
Grace Vycor would do a fine job.
Plumber's putty ought to work, and if you bed the cap right into the putty, you won't need to pierce it with nails.

This question might make me appear even dumber than I really am.... but... can plumber's putty melt and run down the post? Or is it thermally stable?View Image
Hey, Brian!
Your question might make me apear even dumber than I really am, 'cause I never thought about that one.
Hmmm.
Well, it's very similar to glazier's putty, and that doesn't drool off window panes on hot days. At least it doesn't after it's had a few days to set up.
I would say, provisionally, it's probably stable enough for this use, especially as it seems it'll be mostly sitting on a horizontal post-top. Maybe the OP could tell us after he tries it??

Sorry Dinosaur, I should have said I have to cover the vertical part of the posts, not the tops. That being said, here is my two cents on the putty discussion. I think plumbers putty would stand up for use on the tops of posts, it stand up to hot water in sinks. I think glaziers putty would work even better .
I like bedding metal on wood with putty or compound--even when the wood isn't poisoned--because that was the traditional way to do it on wooden ships. And they operate in an environment much more hostile than the average house will ever see, so if it works for boats, it oughta last for houses even longer.
