Yup, use some Permatex or Loctite Antisieze compound... should be available at any parts store... you will only need a TINY amount in each cap... the siezing happens because of electrolysis between the 2 dissimilar metals contacting each other. The compound prevents the electrolysis.
Don't be tempted by "more is better" as it does tend to get and spread everywhere!!
