Absolutely! Dinitrol diligence is key. My chassis is approaching 20 years old and hasn't been welded yet. Thin and runny inside the box sections and thick and sticky on the outside. The thin runny stuff can also be used as a primer, because you can't necessarily get a wire brush on all parts of a Land Rover chassis without taking the whole vehicle to pieces, so where there may be debris, the thin runny stuff soaks in well and reaches the metal beneath, and then you can follow it up with the thick stuff to provide a protective layer, which then really sticks on. When I was young, I used to wire brush (often with a little rotary thing in a Black and Decker drill), then do red oxide primer and hammerite, but that is prone to flaking. Dinitrol's much better. It's also not bad as a wood preservative. Hundreds of uses around the home. In an ideal world it would be piped along the street and delivered to each workshop in a metered supply.
