After the undercoat I applied aluminuim rub+buff on areas that are more likely to be scratched. This was left to dry and then I randomly positioned salt granules. Next step is to spray the O2 covering these areas so I would place some more salt granules. The idea, hopefully, is that when the whole aircraft is sprayed I will remove the salt granules and the chipping will apear.
I will keep posting the step by step of the whole process.
This is the first time that I am using this technique so, my learning curve is still at its infancy
Brian, if you have some advice or you notice anything wrong in my aplication please point out.
