The price is right and anything you can do to prevent corrosion in the battery bay will help. Here are my questions.
- It doesn't say how often or how you know it's time to replace the mat.
- It says the mat contains felt. As you know water will enter the battery bay and if the felt gets wet when driving in the rain will it hold the moisture preventing the bay from drying out.
I suppose you could do the same thing by sprinkling a box of baking soda in the battery tray and adding a little water to disperse it.
Let us know how it works out.
