First time I tried as you should, do so in a spot you will not notice because the applicators aren’t great in my opinion and you dont want to ruin car. In my first test spot I didnt shake the pen enough so the paint came out darker than it should. Also the paint globs together. Shake the full minute. Because I noticed the paint either won’t come out or bleeds too much with the pen & the brush is no good either; I used the cap top for spot treatment. I put a drop on plate, used the clear white cap that looks like a marker top and and dabbed that angle top part to get to get some paint on it. Dabbed to the chipped spot and because the top is flat, you can carefully smooth out if it globs. Paint matches and fixes chips in paint, just test out first. You may need buy clearcoat too, but I only need it for a bunch of little spots dispersed around the car. Not enough to warrant any more work or money; so i hope the color holds over time.
