Hi Andy, I agree with Ashley about the primer, I used it and it’s lasted for years and cleans easily.
Clean the plastic very well before you apply the paint, it doesn’t like any grease, even a finger mark.
If you want a conversion chart, google humbrol tamiya conversion chart, you will have plenty of choice, either online or pdf.
