For these modifications I used the same Krylon 1401 Bright silver paint that I did for the grilles along with the same Krylon clear paint. I experimented with using an airbrush and factory touch-up paint for the windshield sprayers and gauge trim and although the results looked good, an airbrush would definitely not have been practical for the side skirts. Besides, the spray paint is cheaper per can than a bottle of touch-up paint.
For each mod, basically the instructions are as follows: Remove the piece(s) you want to paint, apply primer, color, and clear, let dry, and replace the piece(s). I know I know, kinda complicated.
For the windshield sprayers, the tube on the underside of the hood
pulls off from the sprayer, then squeeze the tabs, twist, and remove.
Be sure to plug the holes for the washer fluid when you paint them
For the door handle trim, remove the screw holding them in, pull
them off, paint them, put them back on. Remember to paint the screws
though or it won't look as nice. An additional tip is to apply plenty
of clear coats so if someone's fingernail accidentally scrapes the trim
piece, it won't take the paint with it.
To paint the gauge trim, remove the two screws above the gauges,
take out the trim piece, undo the four screws holding the rest of the assembly
in, unsnap the clear piece and the back trim piece, unsnap the gauge trim,
set aside the idiot light pieces, and paint. Re-assembly is, of course,
the reverse of the above procedure.
Finally, to remove the side skirts, undo the three plastic screws on the underside of each piece, remove the panels, and paint them. I used once can of paint and one can of clear per-side skirt to ensure the paint would last. Be careful removing the screws since they will strip out extrememly easily. If they do, break out the pliers.
I left the side skirts off for a week to make sure the paint was fully set before I exposed them to the road. They did eventually chip after about nine months but I just sanded them down and repainted.
