Door panel tech tip.

Excellent info. It is important to note when building any vehicle; anywhere that dirt or water can gather (including simple condensation) it must be vented hopefully on bottom. Most of the common rust on these vehicles could have been prevented or greatly reduced if the vent/drain holes were kept clear.

Even if you look at the parking light lens you will note there is a small gap at the bottom. Even though there is a gasket on the lens it still must have a vent to prevent condensation buildup. This is especially important if you don't live in the desert.
