Suzuki SJ413 Samurai Jeep - Floor Rust Repair 1 of 3.

Suzuki SJ413 Samurai Jeep - Floor Rust Repair 1 of 3. One place a Suzuki SJ413 Samurai or Jeep will rust out is the floor because rain water or mud can accumulate on the floor and puddle there until it rusts out. That's what happened to this Suzuki Samurai SJ413 due to a tear in a plastic window (that has been since replaced). The floor on the Suzuki Samurai (Jimny SJ413) is almost 0.100 thick or close to 12 gauge steel sheet metal. The first step is to cut out the rusted weak area of the floor. Then grind the metal around the hole to clean steel about an inch all the way around the hole. Next step to to take some paper and trace the size of the hole. I also cut out some cardboard to check the size of the replacement steel patch again, to make sure I have the right size. It is always better to measure and check twice before cutting any steel. The next step is to lay the cardboard cutoff onto of the raw 12 gauge sheet-metal and then spray paint over the cardboard template so you know how big to cut the patch. The patch will be about 3/4 a inch bigger than the template and overlap the floor in the Suzuki Samurai (Jimny SJ413). I bought a gallon of Magnet Paint UCP934-01 Chassis Saver Paint in silver versus buying POR15 in black. On Amazon a gallon of Magnet Paint UCP934-01 Chassis Saver Paint in silver costs $93.00 versus a gallon of POR15 in black that costs $165. Quality seems about the same and shipping was also less money. A gallon of Chassis Saver or POR15 is enough to do a few cars.
