Grease and air fork seals
I am about to replace an air cap assembly (top part that includes the shrader valve and threads to the crown) on a Duke 03 fork but before I do it wanted to check that I can use any grease on the threads of the cap and not damage the seals. Can I use marine grease or should I use something else? I don't think the marine grease should affect the rubber but I rather play it safe. Thanks.

why not use dielectric grease? it lubricates, conditions, and protects o-rings/seals as well.

I don't know how marine grease reacts in suspension oil but I have heard that you shouldn't use White Lithium grease on suspension forks. It apparently gets gummy in suspension oil and can clog up damping ports. If you aren't sure you should probably go with a safe bet and buy some suspension specific grease like Slick Honey. The o-rings on suspension forks are fairly resistant to petroleum products so marine grease probably won't ruin the o-rings.
