What top coat should I use?

Hi, and Merry Christmas to ALL!
I just bought a Kyrios FG as I want to experiment a little with an airbrush. What I want to do is to panel line this kit with a Gundam Marker Fine Tip (which I heard is enamel) and to detail it with Gundam Markers (acrylic). And finally apply flat top coat with the airbrush, but I don't know which one would be the best. From what I heard there are three options: Enamel flat clear, lacquer flat clear and acrylic (Tamiya Flat Base+Tamiya clear). So, I'm looking for advise as probably someone had tested this.
Thanks a lot in advance.

finnaly found someone else who bought FG kyrios (I have both FG and HG)
for those of you not airbrushing, Tamiya TS-80 is your best bet.
for the airbrush, id recommend a mix of Tamiya flat base and Future Floor Finish. future is a high gloss acrylic, so mixing in different amounts of flat base will affect how glossy the finish is.
id also recommend testing out the lacquer, though i avoid most enamels now.
I would just use Tamiya clear spray cans. I've used Testors in the past and I have to say Tamiya's better :D
