Spray Paint Help

ok so i stripped my FS3 and i bought paint for plastic

after applying a few coats of paint it came out pretty nice

but i wanted a glossy look

so i bought a gloss spray paint and applied

the end result:

it was not glossy at all

it felt like it was dusty, like smooth sand paper

my question is

how can i use spray paint for plastic and get a nice glossy look?


bottom right, it mentions how to paint on plastic. Hope it helps.
