The awlgrip guide says 220???

I like to do my final sand with 320 and even 500 sometimes prior to paint. 220 just leaves to much scratches. It works well for knocking down thick high build but I would shoot one more coat and lightly sand with 320 to keep from breaking threw. If you paint over that it will take may coats to hide the white spots. Grey and white are good to alternate as you can see where you do sand threw and makes it easier to see where you applied it at when coating but it will bleed threw if you paint on it like it is in the final picture. The base color makes a big difference in the look of the final coat. Also I like to prime with a high build primer or a base primer. Your last coat should be done with a sealing primer or final primer prior to paint. Big difference in the two types of primer. The final pre paint primer will not sand well but you shouldn't need much sanding on it. I usually wet sand the last coat of sealing primer. Make sure you don't break threw down to the base primer or you will need a recoat. You can paint over what you got here but for the best finish add a few coats of final prep primer prior to your paint work. This is how I do it any way, others may have different ideas.
