Alright, I finally got around to going threw a junk yard and picking up an old brickyard style spoiler for my '98 Monte. I just got it repainted to match my car color. When I go to mount it all up, I was thinking of putting something like lipstick on the holes so when I place it on the trunk I will know where to drill my holes. I would do this for the side fins as well. I was thinking I could use some kind of rubber grommet or rubber washer for ontop of the bolt so its not directly on the trunk lid, and to keep out water. It seems like a simple enough job, is there anything I could be forgetting? Or anyone have any tips?
