Possible to paint a hiscox case?

I want my girlfriend to paint my acoustic case which is a Hiscox Liteflite II. I know painting on hard plastics is always a bit tricky so was just wondering if anyone else has done it or if anyone can give me ideas.
I was thinking to possibly use automotive plastic primer, hopefully it comes in spray cans, to lay down a base and then stencil the design over that. Sounds feasible to me but maybe pricey.

Haven't done a guitar case except for some writing, but I did do a bicycle helmet and I used auto primer and assorted colours, no pics sorry but it looked pretty cool.

You do need to watch bleed on that 'dimpled' type surface of the case though.

Krylon has some paints made for plastics... if you can get the surface clean enough they do work fairly well.

I would prep and paint the whole thing some color to create a "base" for further art to be layered on top.

But really... I just wouldn't bother at all.

Target Coatings SC9000 (super clear polyurethane) is a water based coating that's clear without any amber tint to it. The stuff adhered just fine to my daughter's fiberglass cello case without any primer. The case has bright blue dimpled gelcoat. I sprayed the clear coat in order to seal over some signatures that were done in sharpie pigment paint pens (white and silver). So, as long as you clean and dewax the case, you can probably use regular artist's paints for your design and then clear over it.

Of course, die-cut peel-and-stick vinyl is an option if you have a graphics place that would cut them out for you.
