What kind of clear coat do you recommend for me to buy or does the Honda OEM paint touchup pen come with it?
I keep looking at your pictures and I really do not think you have scratched below the clear level,
These pictures shows the scratches are deep enough to show colour,Royal Blue.
So my line of thought is you will not need to apply any colour,
You will only need to apply colour if colour has been lost, I am thinking that metallic paints have a last clear coat over the colour, maybe 2 coat of clear,
And I am also thinking you should only sand p2000, wet and dry, I wet sand the white damaged chalky layer away, but only wet sand for a minute, and dry out the groove to check, I am sanding in the right place, all sanding should run with the groove, and be gentle, you do not want to break through to colour or undercoat, or metal, once you have cleared /sanded the white chalky layer, you will be able to see if you need more colour,
An important point to note here is the car is a factory spray job, and the surface of the paint on the vertical panels of most late model car is not flat, they call it off the Gun,
I can see in the pictures, the reflection lines are not quite clear, meaning the surface is not flat,
I have no experience with Pen applicators, except some people can make them work, and people like these people, I found on the pen internet site,

I tried to fix a scratch on my new car. Not only did it not work, but it left a super-glue type residue on the car that I could not wipe away with the dry paper towel immediately after applying it to the car. I will have to get the spot professionally repainted. Beware of this product, it can actually damage your car!
And this guy says,
After the unpleasant surprise of finding a scratch on my still shiny 2-year old car, I thought straight away of this product. While I know that advertisements do exaggerate, I thought this still might do something to better the situation without incurring steep body shop repair costs. How wrong I was! This product is practically useless and, despite following the instructions to the letter, just left my car with a raised clear scar-like line on top of the scratch, which is still visible. To make matters worse, the actual construction of the pen is very poor, and the nib quickly jams (it's based on a pump action method to immerse the nib in the 'healing' liquid). In my case this happened after just one use. Please do read, and believe these reviews and save yourself time and money.
But we know some people can make it work, ??.
Again my line of thought is to make the scratch finish or surface over the scratch area, the same as the surrounding area, use a brush, a very small fine pointed soft paint brush, ( set of six fine soft paint brushes is $3 at cheap shop, ) to dab the coating on, ( not long strokes, please note, long strokes lay the coating flat ), using a fine brush, one drop of clear coat dabbed on at a time, will give you time to blend into the surface texture to match exactly what is on the rest of your panel, while not over building the edges,
As for the clear coat, I agree, go to Dealer, and ask for recommended clear coat in a small touch up bottle, or a spray can is good, because you can spray a small amount of clear coat spray into the lid, then dip into that with the paint brush, I tend to dab droplets of paint on then wait a few minutes for those droplets to dry a little, then another quick spray into the lid next time, before doing some more, ( less chance of the weight of the paint to sag on vertical surfaces, )you can leave it 15 minutes, ( if you clean the brush in solvent), if the scratch is deep,
Looking at your pictures, I do not see deep scratches as shown in above picture,
No more sanding required, no pen problems, no over spray, and if you get a really small bottle of solvent for the clear coat, you can wipe out or off any mistakes, until you have it perfect,
And sit in a chair or on a box, level with the scratch, rest the back of your hand on the panel, and slowly bring the brush into contact, and you should be able to see the new clear coat blending in a soon as you start,
Good luck,
