Removing Vent Screens

I want to remove my vent screens on my 2000 SRX 700 to paint silver, any tips or hints on how to remove, i know it's not complicated, just drill out the rivets but i want to make sure i don't f**k it up somehow....thanks

I painted mine white on my srx along with puttin on a white skid plate for my vents i took all of them out of the hood and when i put them back in i use a small allen head bolt with a tiny nut so when i had to repaint them it was easy take off.for the bottom ones i just taped up the belly pan and painted the outside of them works just fine.Now gonna add the rest with some blue and white simmons skis
