I have a pretty nice. Well a couple pretty nice rust holes in my drivers side floor pan. I know that I have two options get a new floor pan for my 93 yj which is 35$ or I can get some metal and patch it. Is the tar type adhesive that everyone says to use as good as a weld job?

I would deffinitely get the floor pan and not just a patch. Because the rust will stretch further than just the holes you see.

And I'm assuming you mean the seam sealer stuff they used from the factory. I've never used it in person but its holding up well on every one of these jeeps I've seen. So I would tack the new pan in at each corner then use seam sealer all the way around. And I would put it all the way around the under side as well.

I'm pretty sure there's some write ups online where they used seam sealer.

I agree with Simon

I just did the entire floor pan (drivers side) in my 94 YJ. Cut out all the rust, trim the pan to size with sheers or a grinder, fit it in position and either do a bunch of tack welds or rivet it in place and hit it with seam sealer.

Not a good idea to use aluminum rivets. Aluminum and steel don't coexist very well.

With the rivet method, at some point the only thing holding the patch on will be the seam sealer.

if you can't weld it get some 3M panel adhesive.

Thanks for all the info and pointers. Still haven't decided which way to tackle this problem yet. Would the floor pan and some self tapping screws and seam sealer be enough? (Don't want to pay my "guy" just to tac weld 4 corners). I'll also add that I'm going to rhino or Herculine the whole inside after to avoid anymore rust issues.

The self tapping screws will work in combo with the 3m seam sealer.

The question is, will it be able to pass state inspection after you patch the holes like that? In Pa. the inspection laws have changed, and they state that if you can visibly see a patched area either in the cab compartment or the frame, then the vehicle is no longer inspectable. The reason that the floor pans that you buy are pre-stamped and go from 1 seam to the other. To be welded in.

Just letting you know before you put all kinds of time and money into it, and have to turn around and have it done right. Maybe your state is different. Laws vary from state to state.

That's going to be my next project. Found both panels on ebay for $75. The. As soon as that's done I'm ripping out the carpet and put bedliner on the whole floor
