2nd question- *If I wanted to do it like a professional, do they sand

One coat is not enough protection anyway, one coat cant get a good
finish on wood. First coat soaks in, not unitil 3 is it realy
protecting. Not until maybe 5 can it look great. 1st coats should be
gloss since gloss is clear, satin finish is slightly cloudy. I would
build coats, sand with 200-220 inbetween, clean with a tack cloth,
maybe the last coat of satin finish if you dont like gloss. Dont
varnish the door warm, in sun, or when it will soon be in sun.
