Thanks for your reply... i've actually just found the 'How-to' section on your site... haha
Will have to get in touch soon for some paints (want to do a homage to Masami Hirosaka on a Yokomo shell)... so glad i've found a supplier too for the chrome - I had a bottle years ago & I used it on everything, but couldn't find anymore when I ran out.
Will have to try again at using the liquid mask - I did try using it on a shell I did recently - but I think that the stuff I was using had gone off
