Your objective is to have minimal scratching from the previous sandpaper and end with a 320 grit finish.
Painting chrome side steps black.
Applying the primer helps the paint stick to the chrome.
It also ensures the paint stays on if exposed to a car wash or heavy rainfall for instance.
To apply the primer hold the can about 3 5 in 7 6 12 7 cm from your item and cover the surface in an even layer.
Before you apply any paint add 2 coats of two part epoxy primer allowing the primer to dry after each coat.
Shop matte black accessories.
Once the primer is dry apply automotive paint to the chrome surface using a spray gun or a spray paint canister.
Spray on a solid coat of black paint primer.
Paint the part with three coats of automotive paint allowing each coat to dry completely before handling the part or replacing it on the car.
Follow up on the entire piece with 320 grit paper.
Tip use a face mask when sanding or spraying primer and paint.
A pit in the chrome left alone will pop out in no time and ruin your paint.
