I'm a lacquer or enamel user, that is for air brushing.
I've tried the water based paints and I will brush them but I haven't
liked the results from spraying them. Mostly Scale Coat II now but I
have managed to squirrel away lots of Floquil. I'll probably have some
when they take me to the nursing home.
I agree on the decals. What I have found however is that if you can
do the research, lettering diagrams, copies of the art work from the RR files
and photos some of the decal companies will work these for you. Being a
SR fan Hubert Mask at Mask Island has been very easy to work with and has done
several of 1930's - 1950's SR decals that are very nice and weren't available
before. So get the info, photos and find a decal printer who will work
with you, you may be surprised.
