Weld-Through Primer Requirements On The OEM Technical Information Matrix

Let's continue our breakdown of the columns in the OEM Technical Information Matrix. The eighth column calls out if the vehicle maker requires the use of weld-through primer on flanges in preparation for welding.

Over the years, there has been a wide variety of corrosion protection information especially in regards to weld-through primer. As you can see from the OEM Technical Information Matrix, most vehicle makers require the use of weld-through primer. The main exception to that rule is FCA/Stellantis, who requires weld bonding for most repair areas.
