We installed salt-treated wooden railing at the entrance to our our home, several years ago, and it was primed within one year, but never painted. Then two years ago, the railing was finally painted, but the paint started popping and splitting all over the place. Last spring, we added more detail to the wooden railing again, and we painted again. The new paint on the new wood is holding up just fine, but the paint has again popped and peeled so badly on the older parts that there are horizontals that no longer even have paint! What can I do to fix this so that it will last for longer than one year?
