How to Prevent Rust on Muffler Welds

Rust can ruin a car, and it often hits the lowest part of the vehicle first. One of the most susceptible pieces to get damaged is usually the exhaust system. Theyre generally made out of welded pieces of pipe; when the weld is exposed to salt or water, it can start to rust. Stopping and preventing rust on welds around your muffler and exhaust welds is an easy task.

Instructions

1

Raise the vehicle using the jack and support it on all four corners using the jack stands. Make sure the vehicle is properly supported before you crawl underneath it.

2

Crawl underneath the vehicle and locate the first welded area on your exhaust. Mask off an area about 3 inches wide, 1 1/2-inch on either side of the weld, with the masking tape and masking paper.

3

Spray the exhaust with the hi-temp paint. This will stick to the exhaust even through extreme temperatures, and also protect the welds from further rusting.

4

Peel off the masking tape and masking paper.

5

Repeat this process for each weld on the exhaust.

6

Raise the vehicle off of the jack stands with the jack and lower it to the ground.
