Thank you all for looking in and the replies - it really does help. When I get to this painting phase I always go a bit slower - I like the paint to dry and cure before re-coating... Thank You Des Martin, FarEast and RAGIII for the comments - really appreciated. Rob, Thank You for your comments too. Just to review exactly how I did it - The first layer was Tamiya Acrylic Aluminium, sprayed on in a fairly thin coat and allowed to dry for at least a week to really harden up. Then at the same session I sprayed a generous layer of hairspray (The cheaper stuff is better, I find) and allow it about 20 mins to dry - it must be dry to the touch. Then I sprayed a coat of Tamiya Black - also acrylic - here a mixture of Gloss and Matt with a touch of grey to lighten it a bit for scale effect. I dilute the paint well with Tamiya Acrylic thinners and literally mist over a few light coats until the black has covered the silver (and Hairspray) completely. Now I wait til it is touch dry - about 30 mins in our hot and dry atmosphere! Then at the same session I attack it with a scouring pad and create the scratches and chips - Scrape for the scratches and grind for the chips! I use the pads with the plastic kind of rougher side, the metal ones would be too rough... The trade name here in Darkest Africa is Zim... The technique is always worth a try, I got great effects creating that snow camo wearing off armour models with it... When I next do it I'll take photos and do a step by step...
Sorry for the long winded reply! Back to the Pup... Masked the black cowling panels and sprayed the underside... I don't know if the colours will be the same to you, but it's a nice deep cream... now all I need to do is mask the rib tapes and spray around them for the deeper shadows... that should take me a few weeks to do!

I didn't forget to do the ailerons! But I will paint, mask, repaint and decal them separately before attaching them... 'sigh" I don't see a quicker way of tackling this....
Regards,
Marc
