Airbrush help...

[Simpo]

Hi guys, did my first touring shell last night, I'm pleased with it but I think I am still missing something!?

After the liquid mask has a couple of layers of paint on it, when I try to peel it, it's starts to lift the paint that is already on the shell. And then ultimately I got paint creeping under.

Does this mean I am laying the paint on too thick? Or do I just have to cut again once I have a couple of layers on top!?

Any help appreciated

Thanks
