The corners of older trucks are given to severe rust damage due to accumulation of dirt, salt and road debris. Repairing large or multiple rust holes requires installing a large part Patch Panel. Pre-made cab corners retain the original design of the corner and take away the need to fabricate a piece of steel to mend the rust damage. Removing the many rust from the truck before installing the modern sheet metal ensures the rust will never return after the repair.
1 Set a cab corner Patch Panel from the truck cap. Move it into position. Trace round the outside of the Patch Panel by using a permanent marker. Remove the Patch Panel.
2 Cut across the marked line with a two of aviation snips. Set the removed metal aside. Straighten the cut edges by tapping across the cut with a body hammer.
3 Clean paint and remaining rust on the body Patch Panel by using a 60-grit flapper wheel attached to an angle grinder. Stop grinding if your metal surrounding the cut is clean.
4 Attach the floor cable of a MIG welder to the cab on the truck. Turn on the welder. Set the warmth and wire speed-according to the chart upon the inside cover of the welder?¡ìCto weld 24 gauge carbon steel.
5 Wear a welding hood.
6 Align the patch panel together with the opening cut in the cab corner.
7 Place a tack weld in one corner of the Patch Panel by holding the MIG gun around the seam, pressing the trigger with the gun and releasing the trigger after 2 seconds. Secure the panel by placing tack welds every 1/2 inch along side seam of the Patch Panel and cab corner.
8 Attempt a constant weld along the tacked seam. Encourage the seam to cool.
9 Grind the weld smooth using a 60-grit flapper wheel and an angle grinder.
10 Tap out low spots within the welded seam with a body hammer to smooth out the body Patch Panel.
