Cheers lads, the chipping was done with Maskol (liquid mask) and the advantage of that against chipping mediums is that it's very quick to do three stage chipping. I did use chipping fluid on the buck and foot wells though.
Thanks John. And yeah Ian basically, I'll do a WIP of the bonnet to show you (hopefully tonight), so I went grey, sponge on the Maskol, light Olive green, sponge on the Maskol, orange. Then rub it all off with your finger after that you can carry on sponge chipping as usual with paint or micro chip with a fine brush but I stopped after the orange.
