Patching Rust Hole in Tub (Pic Included)

While installing my new spare tire carrier, I learned that the "surface rust" I noticed bubbling my paint on my passenger side rear fender was not surface rust but rather rust that had finally eaten clear through the tub from the underside of the fender....

I'm getting ready to Herculine my interior so I need advice on a good way to patch it before I Herculine over it.

What I was thinking was remove the roll bar and cut/grind out all the rust until I'm left with fresh, rust free metal. I then picked up a self-adhering mesh patch at Advance Auto for body repair...was going to grind the paint down all around where I'm patching to bare metal, cut the patch to size, stick it down, and Bondo over it as the patch recommends. Then sand the Bondo down smooth, shoot any exposed metal with primer and Herculine over top of it. I'm not a body man though and I'm not sure if that's a good way...so if you have a better recommendation, please share.

If it were mine, I'd have a body shop weld in new metal. It is important to have solid metal at the roll bar mount especially considering the seatbelt retractor... That needs to be anchored solidly. Bondo is fine to use on holes in areas that don't need to be structurally sound.

I'm not 100% sure but the mount still appears to be solid and the rust hasn't gotten all the way over to where it bolts down. Judging by the way it feels, I'm guessing its bolting to a bracket or something underneath the tub?

Granted when I get the roll bar off and start hacking away, that could be a whole nother story...

Look close in front of the roll bar, you should see a row of spot welds, running left to right.
If I remember correctly those are where the mount and body panels are welded together.

Looking at your picture I think I see one of em just to the left (small circle, not the big one) of the hole in your tub. Most likely once you hit that spot with a grinder you will see that a proper metal patch job is going to be needed for integrity.
