anyone have any advice, tips etc for painting Napoleonic Austrian white uniforms in 10mm of course 

TIA

Use white paint . Sorry I just couldn't resist!

On a serious note, I have seen them primed with white paint, then give a wash of grey or brown ink to add depth and then relevant colours added to hats, helmets etc. Hope this helps?

thanks Steve I shall give it a try 

Sorry but mine started with a black undercoat, wetbrushed with dark grey (so I could see what the hell I was painting), then sleeves, trousers, and crossbelts painted in in white, then the collars, cuffs and turnbacks painted in in the relevant colours. Theyre no prize winners but look the business when deployed waiting for the attack columns of the "garlic eating surrender monkeys" to get across the table to them.

Thanks Gordon, I shall also try your method   , see which I prefer

Looking to start my Austrians in 2013 so watching this one with interest.

I saw somewhere else that someone undercoats black then does tunic, sleeves and trousers etc in an 'almost white' grey and then picks out webbing straps etc in true white which is what I am going to attempt first up.

Most of mine were undercoated in burnt umber and then blocked in pale grey highlighted with white. That was some time ago, though.

I do my 1866 Cuirassiers in white, crossbelts in cream, facings etc in appropriate colours, then brush (not dip) with ARMY PAINTER dark brown.

White, then a wash of brown or Black. I don't use black ink/wash instead I do a VERY watered down black paint. 

SYW (same coats): white spray did make life very much easier. Tho' that was in 6mm, where shading is just an affectation.

Same principle for Khedival Gyppies, Ansar, ancient Spanish, and French for a long time. White Power! (trips over burning cross and gets his NRA uniform dirty)

What I do is white undercoat followed by a base coat for all the little details with a final dip in Army Painter Strong Tone (Soft tone would also wok for a more subtle shade). This is for speed so if you were after a cleaner final look then go back over the white areas with a highlight post dipping. For gaming with this look works well as thy look a bit more 'battle worn' as I imagine white uniforms wouldn't stay very white for long!

Cheers
