Hi Bert,
When are you going to buy your Thruxton? and where? I'm going to 'Burger' in Deurne to order mine tomorow if everything goes right.
And where in Antwerp are you from? I live in the center, just behind the zoo.... Would be nice to cruise around with a couple of thruxtons in belgium. They are hard to spot around here.
And to answer your question... I'm an illustrator, and there are artists supply stores in Antwerp (schleiper on the Belgiƫlei and Papermill at the 'begijnevest') They sell special rubber-like paint specially for airbrush. Don't know the name, but it's easy to use. Just paint it on the surfaces that need to be masked.... spray your airbrush... and when fully dry, just rub the remaining compound away. Easy as that.
If you have questions about the stores, or like to meet someday.... you can allways reach me on
