Masking materials and brands

[Morlock]

I have seen some beautiful paint jobs in this forum and there seems to be some real knowledgable people here. I am in desperate need of some help with masking materials such as tape choices and liquid mask techniques.

What do people use? I am in California and have been using ye old masking tape and find it to bleed horribly. I have also tried using liquid mask with better, but limited results. It seems to leave a nice line, but the effort in lifting it off the body seems to be too much. Maybe I have not applied it to the shell properly.

What do people prefer?
