Question about making a mold for patching rust?
24th May 2007
Ok, im restoring an 86 camaro. Tore out the carpet and there is a rediculous amount of rust on the passenger side of the car at the foot rest. Its kinda got some bumps and unevenness.
This is a low budget restoration, no big machines or warehouses. Just metal, some hammers, a metal cutter, and a welder.
Q: What is the easiest (and cheapest) way to make a mold of the floorpan, say abt 1′ x 1′ area, so i can then replicate it by bending a piece of metal.
I remember in elementary school, we used to do this thing as an arts and craft activity. We’d make this gooey mixture, cut up strips of paper, dump them in, and then put them on something. It would harden in a short matter of time and create a nice mold. We used to make like masks with it.
anyone know what that is called, how to do it, or what materials i need?
Thanks a lot for taking the time to read + reply. Any help would be great!

If you’re talking about paper mache, just use elmer’s glue to saturate the strips of paper. But why couldn’t you just cut your piece of tin and put it up to the floorpan and then bend it in stages, until you get it close? It’s under the carpet, so it doesn’t have to be perfect. Just bend what ain’t right a little bit at a time and keep on fitting it by trial. Just a thought.

if there’s no holes rusted through, sand off as much rust as you can and apply a rust converter. then spray on a primer and a few coats of paint. you can use spray cans for all since it’s covered by carpet. if you have rust holes, cut out rusted areas and weld in new metal. prime with an etching primer an paint. again, spray cans are fine. don’t worry so much about matching the mold of the floor pan, carpet and padding will hide it all. try to replace the metal only where the holes are and not in one big section. if you have to replace one big section, you can buy matching preformed panels at places like Year One.
