Automotive Touch Up Spray Paint

I have a few scratches on the bumper of my Toyota Corolla (the point where I see long black streaks on the bumper where the paint marks to be.) Is anyway I can touch this issue with some spray paint auto Canadian Tire? If yes, do I need to buy cans of other varnish / primer before starting to paint scratches? Thank you in advance.

I use touch up paint DupliColor. It has the same color is very good and easy to apply from the small tube which has an applicator tip as a pen. You can apply the paint with a very precise way. It is available online too. Make sure to clean the surface with an automotive paint dewaxer / degreaser for best results.

Wash the area with a good degreaser like Lighning greased or orange-based cleanser. then wipe dry with lacquer thinner. lightly sand with 220 grit wet dry paper in stripes. hide the body. spray with primer can be sanded. light coats to build scratch. dry. wet sand with 220 then 320 and sandpaper.

you may need to reapply if you sand primer too. Finally finish with 600 grit.

spray with spray paint matched. coats of light to establish coverage. dry. spraying with a clear coat two to three layers, let dry between coats.

you can buff on the wing if you want.

Do not use spray if you have little to zero. Buy touch-up paint.
There is little bottle like nail polish and put it on like nail polish. If you use spray will be very ugly. If your car is new. go to body shop and have it painted.
