Default Mercury Atlas painting question

The Estes Mercury Atlas is finished all bright and shiny, but as I look through old photos, it looks like not all the Merc-Atlases were so polished. It looks to me like some of them had a white body. Is that true? Or is it just a trick of the lighting in those particular photos?

Current build:

The white was frost build up due to cryogenic oxygen. All the Atlas rockets were stainless sheet metal.

Some good photos of the all-natural metal Atlas booster:

A bit of scrolling will be in order.

Neet page. I 'd never known there were Atlas silos in north Idaho. I'd known there was a wing in southern Idaho, and a few years ago I was surprised to find out that a silo was only about 15 miles SE of Boise, just off the interstate.

later...

Oh wow, that is a great site. I always thought the site near Boise was Atlas, turns out it was Titan I. Wish there was an Atlas museum like the Titan museum in Tucson.

That makes sense. So I shouldn't paint one white unless I fill it with dry ice to get that nice vapor plume around it.

Thanks for the pics, John.

There have been discussions in scale competitions on whether to do portions in white to simulate frost. I don't compete so I have no clue whether it gained points or took them away.

You can see the sheet metal under the frost in this shot.

I painted my scratch built so it wouldn't show finger prints Plus I didn't have the shiny mylar...

Soyuz is the same way...you have to decide whether to model it sitting on the pad empty or in launch configuration.

Personally, for maximum "scalishness", rather than painting the booster and reducer I would wrap it with strips of chrome Monokote adhesive film.
