Floor on one side worse than I thought

So I took a wire cup brush on a grinder to the floors I thought were in pretty good shape. "just surface rust I thought. The wire cup brush got rid of the rust and exposed some holes as well.

I did a search on floors and saw a bunch of advice saying just wire brush the floor use a rust converter or metal ready and then por15.

Am I being too aggressive with the wire cup brush on a grinder?

Looking for the clean up process others followed. Should I use something more aggressive like a flap disk?

Thanks,

Steve.... do you really want you bum riding 5" from the pavement on a coat of POR 15? If you have perforations, you have weak floors. Dnn't think I really need to tell you what you should do.

I'm with Peter - you've got holes the only proper fix is new floor panels. Sorry.

Paul ;-)

X3 on replacing the floor panels. It does take significant time but sort of mindless grunt work. While you have the floor panels out, check the crossmembers too. This will be the perfect time to clean them up and get a coat of rust preventative on the inside of them before you put the new floor panels down. It is worth the effort.

If you've got holes in the floor you need to also check the side castle rails near the area your ankles would be if you were sitting. That tends to be one of the worst as far as rust through problem areas and will need replacing as well as the floors. If you have one or two tiny pin holes you may be OK, but as Peter said you need strength in that area so you won't fall through the floors!

I personaly feel you want to be agressive with the wire wheel, the wire wheel won't put holes on good metal, just expose the bad metal. if you arn't agressive you won't find out how truly solid it is.

Thanks, as I expected. I'm not afraid of the work, its therapy for me. Just don't want to over do things. (I already am) I'll hit it hard with cup brush and flap disc and then post pictures. If localized I may just patch it. I think it would be interesting to try to form some of the patches to match existing shapes.

Thanks!

Steve im in a similar situation, still deciding what to do, if I patch Im going to try and fabricate the shape to match the pans. Alternatively I may buy one pan, and cut sections of that out for each side as the pacth areas are very small.
