Welcome to Librarium Online!
I am fairly new to the whole painting aspect of 40K and just finished painting my first Chaos Space Marine. Does it need some sort of protective coat like varnish? If so can you recommend some to me? Thanks in advance.
After you've painted him(basecoat,everything is painted that you want painted,highlights,drybrushing,ect.)and you've decaled him I would base him as well,makes it easier if you've painted the base and then you can varnish him.
You can varnish him,it is not a rule to do it,but it helps protect the paint from dust,greese,paint chippings,ect. I have never personaly done it but some people brush it on the spray it on with matte varnish,I'm sure if you look around more and dig through some links here as well you can find sites that show you how to do it.
I first spray on 2 coats of krylon crystal clear non yellowing spray varnish. I personally prefer a dead flat finish so afterwards I spray with 2 coats of testor's dullcote. From what I understand the glossier the varnish the more protection it will provide. Generally speaking you really don't want a high gloss finish on your miniatures so a satin varnish should be fine.
Just spray even coats and let it dry thouroughly between sprays. Also make sure you are operating it within the guidelines for heat and humidity otherwise you could end up with frosting or worse.

Ultimately it depends on how much you intend to to use the mini. If i is going to live in a cabinet and not toched - don't worry about it.
If you intend to use it, then varnish is a good idea.
Pick carefully - matte will give a dull finish, gloss an almost wet-loking shiney finish. Satin is the middle road though closer to gloss.
Gloss is supposed to be a stronger finish.
Remember- a little goes a long way and if you're painting it on, watering it will help.
If you're feeling particularly tight, I've heard PVA glue dries clear so that may also work as a varnish, though I've never tried it.
Spray or brush - you're call.
Hope this helps.
