No. I had a body shop do it. I did a very small job on my C350 years ago. Didn't turn out so well. Don't think I want to mess with it. Let the professional handle it.
Actually haven't seen it. Picking it up after work today.
Thank you. I actually think the plastic surface was pretty smooth already. I don't think it is as "perfect" as the factory paint on the rest of the body, but it is pretty good. Then again, it is the bottom of the car, it doesn't have to be perfectly smooth.
My 911 Porsche came factory painted bottom. It is intentionally made to look like "orange peel" surface to take the rock hitting.
