I recently reacquired a 78TA that I parked nearly 20 years ago. It sat in a dirt floor carport, mostly exposed to the elements.

I'm not planning to do a frame up resto. My goal is to get it drivable, presentable, and put as much engine in at as the body can handle.

Surprisingly, the body doesn't have as much rust as one would expect. The floor, on the other hand, well that's a different story. See attached photos.

My question is regarding por-15's floor patch kit. I had a lot of success using por-15 while restoring a different car with my dad, so I'm familiar with how to properly apply it. But I'm not confident that their floor kit is strong enough for an entire floorboard. I know the floor is a part of the structure of the unibody.

Has anyone had good success using por-15's floor kit to restore badly rusted floors? Or should I just bite the bullet and pay someone to replace the entire floor panel?

Those floors are way beyond using POR-15 to repair.

New floor pan time if you’re wanting to save that car, it’s a structural element in the unibody that must be replaced.

That car will literally fall apart otherwise, especially so if you’re putting a powerful engine in it. These cars are already plenty flexible, forget about taking a cheap shortcut on the floor pans.

Time to change out those floors!!!

Even a new floor pan with ugly welds would leave you WAY better off than using some kind of patching product, and way safer too.
