Roy Hi, I bought a plastic bag of all different rattle can Nozzles off of E-Bay some years ago, Cheap and very useful and of course reusable,
It is easy to forget which one is which so a separate plastic bag with a word identifier for each nozzle saves the day.
I stopped buying Tamiya Rattle cans and Acrylic thinners when I realised that similar products at a far cheaper price were out there.
We have a Maplins in the Local high street, No Not the Holiday Camp
, Which sells Acrylic thinners by the litre for the same price that Tamiya charges for 250Ml.
"AK Interactive" Make a very good Metal Burnishing Liquid which stains Metal tracks easily and relatively cheaply.
And Simoniz make a large(500Ml) Metal Etch Primer Rattle Can which is ideal for Metal Hulls and Metal Turrets again very reasonably priced.
Any Motor accessory shop will sell you a 500Ml rattle can of Red Oxide Primer for about £5 and Humbrol's 150Ml rattle can Sea Grey ? Don't Ask (27) is exactly the right match for my Russian campaign German armour and their Desert yellow (93) is a very nice match for the Tunisian campaign Armour,
Both of these make a good top coat that will then take an Airbrush finish to top it off,
I have been using some Chalk Based paints recently with good results the only downside being the restricted choice of colours,
The Matte Earthy Greens and Browns look very good especially on Allied Armour.
I usually use a brush with the Chalk Paints but there are Spray cans out there but not easy to find,
Cassart (
www.cassart.co.uk) is where I go for real Paint, Acrylic Matte Black and Matte White in big Plastic bottles which are much better value that the alternative "Tinlets", Very good service and highly recommended.
