The last photo is the only one that depicts colour accurately. The rest look like beige. It is actually a fine metalic light grey with a low gloss. It looks 30's aviation "Old Skool" and I am happy as can be.
I used Dupont 2K and super etch primer.
On the forum a poster says the RV-8 is 310 ftsquared. I used a 5 litre tin.
UPDATE: I had some touchups to do on the wing tips and wheel fairings. The paint appeared as good as new. Seems to be going off OK. Nearly exactly two years since the buy by date. Dunno what the specs are. I am just about getting the hang of painting now.
