Painting
It's easy. First CLEAN...CLEAN...CLEAN...CLEAN...CLEAN. Did I mention...CLEAN THOSE COVERS. Next, take 680 sand paper and lightly sand the surfaces. After you've gotten them good and sanded (no need to sand hard...lightly...very light), CLEAN...CLEAN...CLEAN.
Next, spread them out on the ground. Newpapers...an old sheet..whatever you have. You want to then lightly spray them. Don't get to close, and don't try to paint them completely on the first run. Spray them, let them dry, and spray again. I did mine over an entire day. Just going back every couple of hours, hitting them with the can, and going back in.
Oh, one more thing, you need to purchase HIGH TEMPERATURE spray. I bought mine at Western Auto for $4.99 a can. Worked wonderfully. Any other question, PM me.
