Rear Spoiler

anyone experience slight hair-line crack/scratches due to wear over time. barely noticeable, but curious if due to repaint/finish due to so-so quality workmanship, or normal wear. mb cert. body shop would re-do given warranty, but not sure if worth it. thanks all.

Not really...... I have never seen this happen

Have you ever removed the spoiler and tried to install it again? Sometimes, when a spoiler is removed, it bends (or arcs) the other way and would have to be bent back to normal before installing it back on; otherwise, the spoiler will constantly try to arc into a certain position and over time may crack

What year car and what spoiler? If you have an E63 and are talking about that, I have seen cracks in clearcoat before. it will eventually literally lift off in little pieces after a bunch of time. On a white car, the fin turns yellowish and has to be re-painted.

I don't know that a paint jo b on a spoiler would be warrantied. If it is, then yes get it dealt with. It is just a matter of time. It will likely last a while, but the upper portion will slowly grow hazy with time. It is from the sun's UV and not being able to properly cure the paint job on plastic parts.

They should have used a different clear coat (IMO). From what you describe, it sounds like they treated it as a usual paint job that they would end up baking. Instead, plastic parts just sit so you need a different compound and more layers.

At any rate, if you get it repaired, be sure to put lots of protectant on it. Clay it, polish it, and throw at least three coats of wax on it. That will give you some UV protection.
