rear splash guards

I just put them on my 04 FX4. I did have to drill a hole in the rear but it isn't a big deal. They give you the screw slip nut things so you just drill a hole and then slip the nut over the metal lip and screw in. If I remember right one of the holes, the lower one fit but I had to drill a hole to match up with the top. I think it added 5 minutes to the install.

I don't know what you mean about a paint synbol. There is a symbol for Trash can, socket and then something that I thought was a screw driver or something to pry the plastic lip from the sheet metal. You are right, they mad ethe instructions so simple they take a minute to decipher what the picture means. Some words would have been nice. I did not primer mine but it wouldn't be a bad idea to coat the hole with something.
