Here are the decals

PCM kits are not Tamiya or Hasegawa, they require a bit of patience, lots of dry fitting and fettling, old style modelling.
First of all, I cut the parts from their sprues and cleaned them up, the smaller parts were left with some sprue “tails” so they could be held in small clamps for painting.
Mating surfaces were given a clean up with some sand paper, not there are no locating pins on these kits.

The surface finish looks shiny enough but it felt gritty, so polishing with a nail buffer was carried out.
Then out with the Tamiya tape and some test fitting.

This went very well apart from some small gaps at the wing roots and some overlap on the wing/fuselage join, nothing as bad as the other PCM kits that I have built. I did read that PCM changed the firm who made the plastic parts for their kits to Sword for this one.
The resin parts were given a wash in warm (not hot) soapy water to make sure that they were really clean, the parts were then left on some kitchen roll to dry.
Then it was time for some paint, on this site I found the following:
“For standardization purpose, Tavola 10 ordered that all interiors had to be painted Grigio Azzurro Chiaro, itself probably a finish coat, as it had little of blue. This happened at least by Spring 1942, but probably the same paint was yet in use before”.
As the Re 2005 was a late war entry I decided to go for grey, Grigio Azzurro Chiaro was airbrushed onto the interior parts with an old tin of White Ensign Colourcoats ACRA15, which came out rather nice.
However, digging a bit deeper on Stormo I came across this:
Here in the cockpit of the 2005 was found a light grey-green (FS 24272). Reggiane also used other kind of greens, at least a darker grey-green for inner fuselage and a grass green (FS 34230) for separate parts as ammo boxes or fin (2001)."

And so, the Verde Anticorrosione Mike Starmer Humbrol mix that I made up for the last Italian build was brought out and all were airbrushed again.

50:50 Humbrol 78 and white 34.
This is how it turned out

It was looking good at this stage, it's the next stage that goes wrong with PCM kits, trying to get everything to fit into the fuselage, but it is worth it in the end.
The other tricky bit with PCM kits is trying to persuade the resin wheel wells to fit in the wings, this took some time and patience when sanding but despite being careful I still managed to break through the resin in a couple of places.
