I've read the warning not to use aluminum in direct contact with ACQ treated lumber as the chemicals in the wood will cause the aluminum to corrode.

However, I would like to make deck railing balusters of aluminum conduit which would be inserted into holes drilled into the top and bottom rails.

QUESTION 1: Will painting the aluminum with appliance paint outside and in (as far as the spray will reach when sprayed into the cut ends) prevent this corrosion?


QUESTION 2: If #1 is not possible, is there another way to attach the balusters so that they are not in direct contact with the wood?
