The Tamiya paint for polycarbonate shells is the one. Presume other makes will also specify lexan or polycarb.
Florescent colours tend to look better IMO, but benefit from a coat of white over them (or under, depending on how you look at it) to make colours shine.
Because cans contain aerosol you may have to pay quite a bit for delivery so if you have a local shop better to call there and pick up rather than get delivered. If needing delivery then modelsport have always done me well
