Hi,Guy:Frist let me say wecome to the hobby! Now
to answer your questions.I have been in this hobby for years,(above 50 years)And I have never owned a air brush! I paint my buildings by hand,
after they are built,some paint them while they are still on the spur(the round piece of plastic
that holds the parts)both ways work well.But,for me I prefer to paint them after I build them that
way if I boo-boo,and have any excess glue on the
building I can clean it off with-out damageing
the paint job. the paint of my choich is polley
scale(floquil)as this is water base,and can be thin by water.I have used this paint for years when it was only known by floquil.Now for scenery
I perfer to use artist paint,(available at arts and craft shops)then I use a thin wash of polley
scale paint to high light or darken the scene,to
blend it together.Now should you buy a air brush?
That all depends on how much painting you will be
doing.Will you be painting your own engines and cars? Will you be weathering your trains,building
and other things? If so,it might be worth the investment.I use the polley scale spray paint to
to paint my engines and cars.not a job for the faint of heart.I have done this for years and have it down to a art.But, if you are only going to paint buildings,I,myself,would not buy one.
I hope this helps you.Oh,by the way,most people
think I use a air brush!
Good luck!
