I second Matthew's praises of POR-15. I used it pre emptevily on the battery tray, as well as other places of my '92 GTI 16V. The stuff gets hard as nails once it cures. A trick to accelerate the cure rate of POR-15 is to mist the coated area with water. Due to this fact, it is critical to carefully seal the container once finished, and refrigerate if possible.
