Hi Jason,

In the process of stripping parts of my Ford CMP truck I have seen both red and grey primers used at various locations under the topcoats that were originally applied to the vehicle.

Everyone has their preferences and I fully understand. If you like something stick with it. I prefer single pack alkyd enamels for ease of application and cleanup. Over the years I have used red and grey industrial primers made in Australia by Jotun, Wattyl, and more recently Wagon Paints. They have been top coated with Khaki paint made by Wattyl and Croda.

I have not had any paint failures with those combinations and some of the items were painted 20 years ago.

A lot depends on the level of exposure to the elements of the vehicle. Mine is garaged so I am happy to use single pack primers. In more extreme conditions or locations it may call for more exotic primers. Even basic WW2 primers have held up well for 70 years on those dry outback finds we see in this forum.

Having said that, sometimes it is worth deviating from using only one type of primer depending on the situation. Having read the great testimonials for POR15 I can see where it would be great for inside the split rims to make tyre installation easier. I can also see it being a very good paint around the battery area where acid fumes and droplets can cause havoc to the steelwork.

I may just have to buy a small tin of that!

Cheers,
