The steps I followed were as per what I saw in the video over this web-site:
Clean the scratched area with a clean cloth and dry it.
Rub the scratched area with a wet emery paper (regmark) of 1000 number or hi
gher.
Now clean the area and spay the finishing solvent on the scratched area.
Now put news papers with tape around the area to be painted.
Hold the Paint can at a distance of 10 to 12 inches from the car surface and
spray gently.
Leave for 10 minutes to dry and again apply the finishing solvent.
