you don't have to used that expensive paint if you not wish to. The way round it , if you are after a red base colour is.. Uses a standed primer, then a normal matt red/brown paint, then your top coat colour. if you use etch on metal then a primer that will be good enough. After all you will not be leaving this tank out in the rain for years to come..Or will you
Man will occasionally stumble over the truth, but most of the time he will pick himself up and continue on.
The rule goes like this..Remove any unwanted edges and sand to smooth..Then DE GREASE all before any type of paint is applied. Then you tack cloth the whole model.
Then the metal parts..if it moves (like your swing arms)..then yes it all comes off paint and put back on. If its screwed down and unlikely to be removed again then it stays. Spray with your etch, then the primer colour of your choice,(colour of the primer depends on the main colour top coat you will be using). Dont sand down too much of the primer coats as we are not painting cars here. tanks didn't have that sort of finish on them.
After you have finished with using all your top coats . If you want to bring out lines and start weathering with heavy reduced paint..Put a clear Gloss coat on this will help you out. When all weathering has finished apply your decals. Then give the whole model a Matt or semi gloss clear coat.
Hope this helps you a little.

I'm having real trouble with buying Tamiya 87061 Metal Primer in the UK. Checking net and local model stroes brought no positive results... Please, either link a store that has this thing in stock or suggest a substitute...
Get yourself down to Halfords. In there paint range they have standard grey and white primer which is fine for metal. They also have an etch primer for Aluminium and one for plastic. I have used these for all, models, props and tanks with no problems.
