Hi All,
As I previously stated due to some of the nice comments I've had for the stained Foreign Service Helmet I thought I would do a quick SBS while I was on with it, hope you find it useful.
1. Over the undercoat I roughly paint in white acrylics the base layer, no need to be careful you are not trying to achieve a smooth uniform blended finish.
2. To stain I use oils but have also done the same effects in acrylics. Squeeze out your oils on a piece of card so the excess oil leaches out into the card, I leave for approx. 20 minutes. The three colours I use are Burnt Sienna, Burnt Umber & Raw Umber. I use these straight from the tube they are not thinned or have anything else applied.
3. First coat is Burnt Sienna randomly applied, then with a flat brush, I tend to a Filbert No.2 scrub in and off this first coat until the excess paint is removed. Remember to wipe the brush after each pass as you are wanting to take off as much as possible and leave a staining. If the brush becomes loaded with paint then use a clean one.
Again you are not looking for a uniform coating but a random staining and I tend to work the paint off in both vertical and horizontal swipes of the brush, if you leave a scrubbed brush mark in don't worry it's all part of the character of the helmet.
4. Apply Burnt Umber straight over the top no need to let the first coat dry. Again be aggressive with the brushes and scrub off vertical and horizontal you are looking for random tones in the staining.
5. If you want to show extreme wear such as the helmet rim use a stiffer brush like a dry brush, and take right back so you get an off white coming through.
6. Because the Burnt Sienna leaves an orange tinge in the helmet creases, I then use immediately Raw Umber to brush into the creases and the then straight off.
Don't forget if the brushes become loaded with paint replace them for a clean brush, don't clean them solvents and the re use immediately.
After blending the first stage should look something like this. The good thing about this method you never ever get two Foreign Service Helmets looking the same.
When this has dried I will add to the colours, tones and wear to increase the stained appearance. Will post a couple of pictures of the final helmet later. I hope this has been useful and given you some food for thought.
cheers
Richie
