The next step was to paint the white parts of the car. I started with another layer of hairspray. Then I masked all the areas carefully. I really hate masking but I hate overspray even more, so I took my time here and I double checked if everything was solid. Then I started the chipping.
The important thing here is to conform to the layer that you’ve already done. You need to match the intensity of the chips and sometimes even recreate the scratches that were partly covered by the white paint.
Also, you have an option to go straight to the rusty base or create a more shallow scratch only reaching to the red colour. I tried to do both.
