What are some tips on repainting large car scratches?

Answer by  MechaNick (146)

If the scratch is not throu the paint you can buff this out by hand with a buffing compound. If it is throu the paint you can only hide it faintly by touching it up with the same color code touchup paint.

For very deep scratches it is usually better to repaint a large area. Especially if it is a metallic or pearlescent. THE area will have to be sanded smooth, primed, and then sprayed. The paint need to be diluted down in steps to promote blending of the paint into the surrounding paint.

If the paint is scratched down to bare metal: Wet sand the entire scratch with 400 grit sandpaper, feathering along the edges of the scratch. Apply a primer over the sanded area. Wet sand with 800 grit paper. Apply several light coats of paint, wet-sanding with 800 grit paper between coats. Finish with 1 to 2 coats of clear.

Automotive paint repair should really be done by a professional. A normal person would need to do a lot of research as well as invest quite a bit of money into the necessary equipment. The process will involve stripping the old paint, leveling the surface, priming it, an blending the topcoat into the rest of the paint.

Preparing the surface is the hardest part. Depending on the depth of the scratch, it may be able to be removed with a rubbing or buffing compound and a buffer.
