Shake the paint aerosol vigeroursly for at least 30 seconds
, this will mix all the paint mixture together like the metallics and pearlescent that will have fallen to the bottom of the can. Before you spray the repair with the paint you must first get a feel for the flow of paint from the aerosol, if you don't then you might have the paint running all over the bumper, so spray a test area somewhere away from the car first. Once you can control the paint flow and feel confident enough with the paint apply a thin coat over the primed area and heat up with the air gun. Once the paint has dried continue this process of applying thin coats of paint until the primer is fully covered (usually 3 coats) on the final coat try to flick the paint around the edges of the bumper repair this will help blend in the paint. Once the paint has completely dried you can now apply the top clear coat. Again spray a test area with the clear coat lacquer away from the car to get a feel for the lacquer flow. Spray over the painted area with a thin coat of lacquer and leave for at least 5 minutes so the lacquer can settle and don't heat up. After 5 minutes apply a second heaver coat while flicking the lacquer out around the edges of the paint to blend in, and again leave for 5 minutes then heat up until the clear coat lacquer is dry. Now the clear coat is dry use the 2000 wet and dry paper gently over the repair (not the edges) to remove any high points and to level off. Rub over the cutting compound until the lacquer starts to shine, then do the same with the polish until the clear coat is glossier and shinny. Next rub the polish gently over the edges of the bumper repair to blend it in with the original lacquer. Once this is finished the bumper scuff repair is completed, remove the masking tape, and stand back and appreciate your bumper repair.
