Helmet basic painting advice

[usul45]

Hi again guys! So the Elmers glue trick for thickening up the aerators is going great, now I need to pick your brains about a basic thing. I have a heat divot or deformation just above my trim line and extending under the trim (I'd show pics but I can't find the camera) I need to sand this out and then re-paint. I purchased my helmet already assembled and painted by TE. The paint is pretty shiny but I really need to know exactly what kind of paint I should use on this after I do the divot repair. I found some appliance epoxy paint, and then of course your everyday Krylon stuff, what do I use for the best shinyest and most permanent paint application. The helmet is Styrene. I also wonder what sort of sanding material I should use on the helmet, adn if anybody has any technique suggestions.

Thanks in advance for the help on my bucket!

You should find out what the helmet was originally painted with. Many paint brands react with other paint brands and you result could look terrible.
