Restoring/repainting rear trunk spoiler?

[Chubtone]

My rear trunk spoiler is faded and chipping and has lots of little cracks in it. I removed it and sanded through most of the flat black outer layer. I'm wondering what the process is for repainting the spoiler.

Also, my car had a flat black rear spoiler on it when I get it. It's a 1990 325is. A friend told me that he thinks they were all color coded to the car from the factory. Is this true?

I used plasti-dip to "re-finish" mine and it worked great for what I wanted.

Yes, The standard "is" trunk lip spoilers are color matched from the factory. People spray them with bumper trim paint when they get cracked because it is kind of expensive to get a flex agent paint that matches the color of the car to repaint it, or people like the contrast of the black on the body color. For me it is both. I like to be able to "see" the spoiler, instead of it blending in. Plus, the black bumper paint (has flex agent already so it flexes with the spoiler and doesn't crack) is inexpensive and available at Wal Mart in the automotive paint section. I just painted my coupe trunk lid that I have on my vert (for the 3rd brake light delete) to match the car and now I am going to sand and paint the "is" spoiler with the bumper trim paint to make it contrast.

I've got the same problem. Are you guys sanding down the cracks until they're gone, or just roughing up the surface? Looking at the cracks, it seems like the paint on my spoiler is pretty thick. It'd take a ton of sanding to sand them down. Any advice?

If you don't sand the spoiler down smooth, the cracks will surely show through the finished product....ask me know I know. I painted an "is" spoiler for my 89 that I had but thought I had gotten all of the cracks sanded out. The black bumper paint goes on thin and showed every crack and spot of old paint. I went back and sanded every bit of paint completely off. That ensured that there were no cracks as most of the cracks you encounter are in the paint only and not into the foam of the spoiler. After that it looked amazing.
