Auto torso work can be very gratifying, and yet it tin can be very challenging. It is almost as if you are creating a piece of work of fine art in the form of a sculpture when you reshape and mold car panels. Whether you are pounding out a large dent, working with Bondo filler or glazing over modest scratches, yous demand to acquire a special touch to get the body just correct and set for paint. Get a general overview of what you can practice with body work.

Step 1

Get nether the damaged surface area of a large dent using a hammer and dolly organization. Place the dolly on the outside of the dent and pounding the metal from within to curve the metal back to its original shape. If yous can’t access the rear of the panel y’all may end upward using metal pullers which tin can be set to pull the dent forwards. In more serious cases, the bent panels may accept to be pulled out with special machinery. The object hither is to pull the metal back to its original position, or replace the panel with a new one if necessary.

Footstep ii

Make full over a panel that you straightened out or fill in a smaller dent with a Bondo body filler. You can fifty-fifty utilize a finishing putty that is meant to apply in thinner layers, whereas Bondo can be put on thicker. When doing body work, you want to use as little filler as possible. Y’all’re best off when your metal is pretty much straight rather than built upwards out with fillers, which may ultimately crevice and fall out of identify. Spread on evenly, allow information technology dry difficult and and then sand downward using sixty to 120 grit paper and finish off with finer grits to feather edge into surrounding surfaces.

Step iii

Cut out any rusted sections with a cutting tool if y’all are dealing with rust removal. Then weld in new metal every bit a patch, being sure that you take cut away all the rust start. In this case you will have to fabricate a piece of canvass metal, typically 22 gage, to fit the opening. Yous volition so need to grind down the high weld spots and use a filler to smooth over the new metallic and plumage the edge into the existing metallic.

Footstep four

Sand down scratches, old pigment, articulate coat or smaller flaws using 120 to 220 grit paper to get downwardly below the clear coat and paint. Then you can use a glazing and spot compound which is meant to make full in minor dings or scratches. Apply in thin layers. Expect for each layer to dry, sand it apartment with a fine grit paper and utilise some other layer until the expanse is level and smooth. You lot can use the aforementioned compound to fill in pin holes and to feather edge any slightly crude edges left behind from body fillers.

Step five

Sand with 400 grit newspaper or use a scuff pads when no real body work is needed, but yous just want to set up for primer and new paint. Dust off all sanding droppings or blow clean with an air hose. Always use a wax and oil remover before spraying on any primers or sealers.

Step 6

Block sand using a different color primer as a guide glaze to become a very smooth surface later body work of any kind has taken place. Cake sanding is time-consuming and tedious, simply must exist done. Your flexible sanding block should be at least 12 inches long, and when sanding over primer you should utilize anywhere from 300 to 400 grit wrapped around your block. Utilize long strokes in different directions with equal and house pressure. A guide coat of a unlike color primer should be applied over the original primer. As you lot cake sand and begin to remove the primer, yous volition see any low spots that remain untouched of the original primer. These low spots can be filled in with coat or filler or sometimes farther block sanding volition level out the area. The old proverb for a perfectly smoothen body is, “Once you call up yous are done block sanding, exercise it again, and then one more time.” The perfect paint jobs and smooth bodies took a lot of hard work to obtain which included a lot of “cake sanding.”

Step 7

Spray on primers and primer sealers on a regular footing during body piece of work. You should never spray primer, however, until you’ve sanded the old painted surface, and so you lot should use an oil or grease remover, laquer thinner or other oil-free solvent before any primer is applied. Terminal sanding of primer earlier sealer should be done using a 400 to 600 grit paper. A final wipe with grease or oil remover solvent should be used ane more time here before primer sealer is applied. Primer sealer is used as a final spray just before paint is sprayed on the vehicle, which serves to seal in the primer and give you a very smooth stop.

Stride 8

Survey the body impairment commencement Earlier jumping into any body work, always be sure to survey the damage, program your moves ahead of fourth dimension and have all the supplies you will need in advance.
