Hey guys I was wondering how I should go about refinishing GPO grills? I want to match them with the bumper/lower fascia color (gray).

Since you havent painted...Get something else to practice on first. Something you don't care about messing up.
After you get the hang of how it sprays, and all that jazz, time to move onto your GPOs.
*This is assuming you use rattle-cans, and let the paint fully dry between coats*
-Wash them with a grease/wax remover to make sure they are super clean.
-Sand them down with the appropriate grit sand paper (if there arent any bad scratches, or paint failures, 600-grit will be fine)
-Wash them again and dry them. Wipe them off to make sure there is no paint residue left on.
-Spray a light 'tack' coat of your paint. (This is a very light coat, not meant to put much color on the piece)
-Spray a 2nd light coat, slightly heavier. You should have a little coverage at this point, though not much) Make sure to get the corners and little nooks too.
-Spray a 3rd, medium coat. Aim for 50% coverage or so, without the paint looking wet. If it looks wet, STOP. You'll end up with sags and runs if you spray too heavily.
-Spray a 4th, medium coat. Aim for 100% coverage with this coat. Again, if the paint looks wet, stop..it's going on too heavily.
-Inspect the piece once it's dry. If there are any light spots, or non-coverage, spray again to make sure it's completely covered.
-Once it is totally dry, you move on to clear coat.
-Spray a light 'tack' coat.
-This time, spray a medium coat. It should looks a little glossy.
-Spray another medium coat. Go for 100% coverage with this coat.
-Spray a 'wet' coat. This last coat of clearcoat should look wet and glossy. But don't spray too heavily, or you'll get it hazy and have runs.
*A simple rule of thumb with clear coat...The last coat you spray, while it is still wet is how your final product will look.
Let it cure completely. Then polish them out, and reinstall!
both made of abs plastic so yeah
