What kind of paint should be used for RCA DTA800 DTV converter box for RCA CTC121 TV?

[waltchan]

I just received my $40 voucher and used it to buy the RCA DTA800 DTV converter box at Wal-Mart to use for my 1984 RCA CTC-121 TV. The TV and VKT650 VCR are silver. But the box is black color. Not a matching color. I think I will paint it to silver. Assuming I can match the color, what kind of paint should be used for the DTA800 converter? The exterior shell is all plastic, not steel, so I cannot use Rust-O-Leum. Thanks for your help.
