Any good products out I should know about!New one to much$$$

There is really nothing you can do for it once it starts to go other than replace it. I would highly recommend one of the fiberglass replacements out there that won't crack or warp like the original one does.

If you just try to patch or repair yours, it won't take very long at all and it will be cracked again.

Cheapest way out is to just remove it, but the car looks naked without it IMHO.

Lots of information can be found on these boards...

This has happened to my wing too. In a time span of only 1 year, despite being kept in the garage, the top rear surface developed a huge amount of cracks in the paint for no apparent reason. Replacing it with a fiberglass one is too expensive at the moment so I found a way to hide the cracks.

Waxing & polishing, etc. left white residue in all the tiny cracks and they were quite visible. To hide them I made a blue wax. Now all the cracks are as blue as the paint and they are invisible until you get close to the car. Looks much better now until I can replace the spoiler.
