Gordon,
I didn't use the acrylic sides on my car, rather I cut styrene sides to replace
them. If you compare the acrylic sides to scale drawings, the dimensions aren’t
prototypically correct. If that doesn't bother you, by all means use the
acrylic sides. Since you want to use an acrylic paint, I recommend you either
media blast or lightly sand the sides with #600 grit sandpaper to provide tooth
for the primer and paint. DO NOT use Tru Color primer, it won't stick to resin,
and it probably won't stick to acrylic sides either. The best prime available
for resin and probably acrylic is Tamiya Fine Light Gray Primer. It's a lacquer
that's available in rattle cans. Don’t confuse it with Tamiya Light Gray
Surface Primer - look for the word FINE in the label. You can over spray the
primer with acrylic or lacquer paint. Pullman Green is in the eye of the
beholder. I did a comparison of Floquil, Poly Scale, Model Flex, Scalecoat II,
and Tru Color Pullman green, and to my eye, I prefer Scalecoat II. Since I
built my cars before that comparison, I used Floquil on one car and Poly Scale
on the other. Since then, I've gone with Scalecoat II on the eight converted
troop kitchens (four with windows and four with plated windows) and four
express boxcars. The BA-19A cars were sprayed with Dullcote. The Walthers cars
were sprayed with Model Master Clear Flat. Take into consideration that
lighting for photography was different, so that affects color shades. I did one
BA-19 in shaddowline, using Krylon Flat Aluminum in a rattle car for the
silver. That color isn't in the current Krylon line, but you can probably find
something close from Krylon or Rustoleum. I've attached photos of the color
chips and cars in all three shades of Pullman Green and the shaddowline BA-19
for your comparison. The shaddowline decals are described in RMC June 2015.
BA-19A 1045 was kitbashed in styrene (Floquil paint), BA-19A 1023 was
scratchbuilt in wood (Poly Scale paint), and BA-19 990 was scratchbuilt in
styrene (Krylon Flat Aluminum). The BE-1 troop kitchens and XM-33 express cars
are enhanced Walthers kits (both Scalecoat II). The color chips were
photographed under 5,000 K lights. The colors you see will depend upon the
color correction of your monitor.

Subject: [CBQ] Painting acrylic car sides
group...I am doing the Havelock baggage car kits and would like some advice on
painting the acrylic sides. What prep if any and what paint adheres best. I am
looking at Model Flex for the Pullman Green and Tru Color for the silver over
their light primer. I can grit blast if necessary.
