Skip, glad you are still working on your van, getting it ready for the
season.

I have been using the Rust-Oleum paint you are talking about except in
Satin Black for Westy fiberglas bumpers and grills for a few years now
(5).  It is holding up and looking really well and I would highly
recommend it.  As with any type of paint, it is all about preparation.
I usually use 3000 wet sand paper to sand any grills or even the bumpers
if they just need a freshening up.  This gets rid of any small
imperfections, gives the paint a good surface to grip, and gives you a
smooth end result in your finish.  You should clean the surface with
either some mineral spirits or surface cleaner that is for painting (I
use Sikkens surface cleaner), it will dry really quickly and leave no
residue behind.  Then just put the paint on it thin even layers.  A can
should do a set of upper and lower grill with some left over.  Two cans
will do that and a front and rear bumper on a Westy including the side
panels on the front doors.

I like the Satin because it really comes out as an almost semi-gloss
look to it which I imagine is what the factory had on there in the first
place.

If I can be of help to you in any way (parts or advice) as always feel
free to call on me.
