I have a '99 tracker and have been thinking about painting the lower part of the doors and the bumpers silver like some of the fancy Vitaras. Have any of you ever done this?

Clean them well to get off armoral, or any other oily, greasy shine product, coat with a plastic primer & paint

I did that a year ago. Just clean it up good and wipe it down with methanol or rubbing alcohol and paint with Krylon Fusion paint for plastic, no primer needed and it looks great. I used the black shimmer but there are other colors. The shimmer has some texture like the bed liner coating but looks much better.

Krylon Fusion is the goods.

OK, looks like it's gonna be Krylon for the paint, just one little thing first. The plastic trim pieces on the doors are pulling away on the ends, I don't know why, it just was like that when I bought it. How do I fix it?

Yep, the Krylon works great.  I recommend cleaning the plastic to remove any grease, oil, etc., then lightly "scuffing" it with some sandpaper.  I did this on my flares and plastic bumper pieces on my Ranger and it worked great.

For the trim....adhesive....they should sell it at walmart or the auto parts stores.

Any special kind of adhesive? It looks like the original was some type of sticky tape. I like the idea of adhesive because I could just squeeze some under and press it back.

Seems like I have seen some stuff that is actually called "trim adhesive".  Comes in a tube and should work for you.

Lightly can't be over-stated here. I scuffed some plastic bits way too much with rough sand paper...

and it WAY showed up when I painted it the first time 

Im in the collision industry whenever painting smooth plastic non textured you should clean w a wax and grease remover from oreallys or wherever laquer thinner will work just dont get to crazy. scuff the desired paintable surface with a high numbered sand paper 400   500   the best would be a red scotch brite pad done by hand clean and krylon!!!!!  If your painting textured plastics dnt scuff or sand just clean really really really gd go to an automotive paint store ask for plastic adhesion promoter put 2 very lite coats on your textured peice let dry n krylon!!! dnt sand at your textured pieces or youll make it show in your paint...   remember higher the number of sandpaper the finer you can base over 320 grit but in an instance where a krylon or rattle can is used i would use a 4 to 500 or the scotch brite pad all your looking to do is scuff the old paint or clear to give the new sumthing to adhere to and it dnt take much hope this helps thanx jd
