Hello.
I bought a car with a "key" scratch across each side, as you can guess big scratch attracts other ones. I couldnt look anymore and decided to do something with this. I ordered a touchup which includes base coat and clear coat. I put the case on the scratch but not sure what to do next, I think it looks even worse at the moment.
Here are the steps that I made:
1) I took the car to the car wash
2) I washed the scratch with a wax remover prep solvent
3) I put 3-4 coasts (depends on how deep it was) on the scratch with a brush
What should I do now? should I put the clear coat on it or should I sand it a little bit to level out the base coat?

Here is how it was before and right now.
