Mark,
I completed a body off resto on my 74 Ghia and used POR-15 on the entire chassis, to include new floor pans, front beam, etc., the wheel wells, the underside of the engine bay, and inside the door panels. Stuff works great. Two cautions. One…when you apply the POR-15, make certain you don’t get the POR-15 on any bolt threads or studs because you won’t get the nuts to fit and it is almost impossible to get off. Two…cover yourself really well because that stuff is even hard to get off your skin.
I’m going to use POR-15 for my TD chassis. And run some Marine Clean through the fuel tube to make certain all the varnish from old fuel is gone and the fuel line is squeeky clean.
