Wallace, the pro`s and contra`s of the gloss-stain-matt paintjobs had been discussed massivly. Out of my experience from nearly 40 years of modeling I just can say:
Even if the real ships had been painted gloss and you look at the photographs of them- just a distance of a view meters make the glance disappear.
Models painted in gloss colours will just catch up reflections from lights (even the sun) and therefor they look toylike to me.
Satin finish is o.K. for boats just slipped out of the yard. Two days on sea and the spray will give them a matt finish.
So I prefer matt finish on all of my boats. It looks more realistic to me.
If you are in doubt, just have a look on the photographs I have send to you from the build of my Sir Lancelot.
If you are still in doubt, the spray one layer of satin or matt varnish just on one side of your superstructure and compare it after drying with the other sid. If you like, go for the rest. If you don`t like, just spray over in gloss colour.
Just my penny.
