likely hood is that the site bottle you used was syphoned (intentionally drawing liquid) or just a standard bottle with neither anti / or syphon. that would definatley cause you a number fo problems.
wait till youve tried the marker on a bottle you know is anti-syphoned before you go spending any more money.
