Those molotow paint pens are totally different. You lay it on real heavy. I bought a 30ml refill, and i'm using an airbrush. The molotow product doesn't require any base, or primer, just put it on. I'm working on a housing that was painted silver, and it sticks, and covers. A different process, and a learning thing. Stardustcolors.com now sells the UK stuff here in USA. I was talking with them about a month ago, and they just sent me a price list. Id suggest if you try a product, go small and see if it's what you want. In the last 4-5 years I'm it for over $500 just trying to find something that works for me. I keep trying, and hope I'm getting closer to something that works.
