Repair Rusted Truck

First, the amount of rust present on the truck’s frame needs to be determined. If a substantial amount of rust is noticed, then inspect the whole frame. If possible, a grinder or a cutting torch can be used for removing any welded pieces from the frame. This will be helpful in making the sand blasting the whole frame much suitable.

Step 2:

Try to remove the old paint and rust as much as you can. A sandblaster can be used for this purpose or it can be manually sanded for exposing the metal. Damages such as blistering or cracks should be checked.

Step 3:

Use a grinder, hacksaw or torch to cut away the rusted parts.

Step 4:

Make a pattern of the pieces for repairing the metal patches that were removed. Many people prefer using a cardboard piece and sharp small knife or a blade. It must be made certain that the pattern fits in a perfect way.

Step 5:

Now the cardboard pattern has to be placed on a metal piece and paint has to be sprayed around it. Then the cardboard has to be removed from the metal, now you will have a perfect pattern. Cut out the metal patch and sand around the edges of all the metal patches to make it smooth.

Step 6:

The patches as well as the whole frame must be made rust-proof. Apply rust proofing to the whole patch and frame. This is a good time to apply rust proofing because all the areas of the frame are easy to access.

A lot of rust-proof products are available in the market. The manufacturer’s instructions have to be followed when performing this step.

Step 7:

The metal patches have to be welded. A strong weld has to be created for durability. Keep the weld similar to the original, if not then use a standard weld. Sand and grind the weld to make it smooth. A primer has to be applied to the whole frame, give some time for it to dry and then a coat of paint can be finally applied. Now you are done.
