I bought trucks for light truck division of FOMOCO and noticed that after 3 months in the parking lot, never driven, rust started to appear on certain parts of the 73 Ford Econolines. Checking the areas rusting, I noticed no paint in areas parallel to the automatic assembly line paint spray heads. So, when I bought my 73 Chateau Club Wagon on “A” plan, loaded with every accessory available, I immediately painted those areas that either had no primer, or just primer and no paint, or bare steel. That was done within the first three days I purchased the van. Next was a trip to my local Ziebart dealer. Drilling rockers and doors, Ziebart, a mixture of heavy oil and paraffin was applied. The olde van has been on the road now for 46 years with over 400,000 miles on it. Areas Ziebarted near hot pipes and mufflers has dried out and flacked off, so I stripped those areas with mineral spirits and underneath, the factory undercoating primer was like new. I applied gloss black enamel, via spray can to those areas. Even with such a good undercoating system, frequent washes during the winter to remove salt and magchloride is a must. If I had not spent the $300 dollars back in 1973, when the vehicle had not yet been driven in the rain, today, there’d be nothing left to it, due to the ridiculous design of the underbody with lap and seem jointed welds that had no paint on them. I’m glad Ziebart is still around. It is an excellent undercoating system.
