That looks downright NASTY:eek5:

See how deep it is, it might be "grindable" if there is such a term.

Damn, thats rough! I would have thought that was a floorboard of a car from the 60's if I didn't know it was from a Miata. As I think I see a few places already rusted through, that might be a tough repair. I'm no sheet metal man though.

id get a new shell... they are cheap

As much as it sucks, a new shell is the best option.

Holy shit, car must have been in a flood. I would just spray it with rust fix to get rid of the rust. Unless you want to get a new shell for it

I don't think thats going to regrow the 2lbs of metal the rust has eaten away. I also vote new shell. You can buy mine if you buy the other $4500 of other stuff thats attached ;)

A thin layer of carpet will cure that. Out of sight, out of mind!

or mine... with $20k+ and my soul attached to it... ill throw in a blow job or 2 from hustler

Hey, that isn't the point here. The point is I will sell my "shell" for $4500 :fawk: Keep your irrelevant posts out of this thread please.

Ya know, Im thinking I could grind away as much as possible, patch the holes, spray it with some sealer and then just run with it. It should last another few years before it really becomes an issue. Besides, I'm planning on getting an NB in the next year or so and then I wanted to turn this car into an autox/ track rat.

Please post vids of it getting set on fire in a blaze of glory. Other suggestions include driving it into a burning barn, or driving it off a clift and having it explode on the way down.

bondo products? looks like it works wonders for rust holes.

Not on a structural section with holes.

Dayum! I think you could probably fix this if you had to...but like you have already said as well as many others, its probably more cost effective to just get a cheap shell...this is why I like the miata so much, compared to cars with similar performance (After the miata's been turbo'd of course), parts are plentiful and cheap!
