Default How should I tackle this problem?

So I bought the heat barrier, the sound barrier and the carpeting is on the way. I pulled out all the old nasty carpet, jute, and some other stuff that may have at one time kept noise and heat out. Now the problem:

Under the driverside carpet I discovered the floor pan has a nice layer of rust. I don't think it's too deep but I want it gone. What's the best route to remove this? Chemicals? Sandpaper? Grinder? Brush? Then after gone should I paint it and with what? I was thinking sound barrier paint.

Thanks,
DB

If it is not rusted through, then wire brush it (electric drill), clean with solvent, and paint with a good rust inhibitor commonly sold at the parts places (Autozone, NAPA, Advance, etc.). I believe I used a "special" aerosol specifically formulated for this application.

I then, went to Lowe's building supply and bought a roll of Reflectix 25-ft x 24-in Radiant Barrier Item #: 13357 | Model #: BP24025
at a much lower cost then barrier kits from most online corvette parts dealers and it works!...NO HEAT COMING UP FROM UNDERNEATH THE CAR THROUGH THE FLOORBOARDS.

Most carpet comes with a jute backing already and I experienced no fit issues with carpet or seats.

yeah, that looks good. for me when i tore up all my carpet and found the rust(make sure its not getting wet anymore from heavy rains, this could be from several different issues) I just scraped excess, vacuumed it, wired brushed everything some to loosen smaller stuff, vacuumed it, then just spray painted it with a couple coats of hammerite by rustoleum. cant see it and its not getting wet anymore

Had the same issue with my passenger side. I confirmed the structural integrity of the pan by tapping it with the side of a hammer head. It would bounce loose any flaking rust. I then scraped it and wire brushed it. I felt the metal was in good enough shape to keep. The bottom had no rust. I don't know about prep or application of the POR 15 as by body shop guy did that part.

The finished product was impressive.

You never know. Bought it from a guy in Ft.Meyers, FL. Had lot's of bubba infection and general lack of care and maintenance. I may not have bought it had I done a more thorough inspection. To late for that now. I nearly matched the big 'O' on spending the last couple years bringing it back to life. Except I think I might be better off.

Thanks. What "solvent" did you use to clean Scorpion? I was thinking paint thinner.

Use a powered wire brush to dig out the rust. If it is solid when you get done, paint it with POR-15 or other good quality metal paint. If it is not solid, you can do the "steel (or aluminum) panel and Pop-Rivets" method, or all the way with the "cut it out and weld in a new panel" approach.

I hope you find very mild rusting.
