    any solution to my carbon fiber spoiler?

    hey guys, recently my CF spoiler blade started showing some strange effects, dont really know what to call it.

    It's not really flaking but you can feel it in some spots if you run your fingers over it.

    I took it to my bodyshop and they told me that they were affraid to sand it as the clearcoat looks really thing and they were affraid of getting through to the fiber and damaging it, but we decided to try wet sanding in a corner anyway. They did some VERY light wet sanding (like 15 seconds of 1500 grit) and it didnt really do anything.

    I sent the pictures to the manufacturer i bought it from to try and get some answers (I'm hoping they tell me they will warranty it).

    I'm pretty sure they already told me once that it's got a clear coat on top of the gel coat, going to double check that info right now.

    here are the pics, they are very big to preserve detail









    I hope someone can help me out

    Looks like the clear coating is failing.

      It does look like CC failure.....

      At least it looks like it when comparing to the photos in this thread.....

      Check with the maker and see if it's under warranty. Then see what it is, (gel or clearcoat).

        On a carbon fiber hood I used to have it started cracking around some edges and it looked a lot like that, but it could well be cc failure.

          I would agree. It looks like cc failure.
          quality creates its own demand

            well, good news!!

            i went ahead and wet sanded it with 1500grit, then compounded it by hand and afterwards whipped out the DA with an orange LC pad and used some meguiars #9 swirl remover and it removed 95% of the problem!!

            Oh and i followed all that with a fresh coat of NXT wax

            so apparently MOST of it was still on the surface.

            Now i wanna get a fresh new clear coat sprayed on there to prevent it from happening again. I'm assuming that I'm correct?

            I will upload pics of the results tommorow!

              As long as you keep it waxed, and washed properly, I don't see a reason for the CC to fail in the first place.

                I just found out there is a spot on the roof of my Mustang where the paint is cracking. It happens.

                  Here's a cropped out section of one of your before pictures I placed into your photo gallery here on this forum.

                  This is not clear coat failure




                  This is some kind of cracking or crazing.

                  Most carbon fiber components do not have a clear coat finish, if they do they cost more because that's an extra step. Most carbon fiber components are straight resin, that is the surface you're working on is also what the component is made out of.

                  Straight resin will tend to oxidize if not continually maintained. We have a lot of people bring cars to Meguiar's with oxidized carbon fiber components and in most cases the paint on the car is swirled and scratched which means the entire car is usually neglected, that is it isn't maintained with any kind of polishing and waxing and the results of the neglect is the clear coat paint gets swirled and scratched and the carbon fiber components become oxidized.

                  The oxidized components stand out like a sore thumb because most people get used to swirled out clear coat paint as that's the norm for most daily drivers.

                  If your wing had a clear coat you would have probably noticed a layer sanding off as you sanded, if you didn't notice a distinct layer sanding off then you likely have straight resin. If that is the fact, you need to polish and wax this resin material often to keep it from oxidizing.

                  Did you ever see any carbon fibers poking out of the resin after sanding?

                    Re: any solution to my carbon fiber spoiler?

                    you are right

                    the manufacturer told me that it has a "weatherproof" gel coating that has UV protectors in it.

                    well apparently it didnt do it's job all that well since this happened.

                    i even waxed it every couple of months, apparently it wasnt enough, i'm gonna try to do it more often.

                    how often would you say is enough?


                    no, i did not notice an extra layer coming off when sanding nor did i see any fibers poking out.

                    Except at the edges where they joined the top and bottom part of the spoiler together and it seems that the gel coating is very thin, but even there there wasnt anything poking out, just very thin.

                    i'm glad to know that this isnt a clear coat failure. Would you think it would be a good idea to get a new layer of clear coat sprayed on? I was planning on getting that done next week.

                    Oh and i forgot to post the after pictures, there really was a HUGE difference



                    Lastly, thanks allot for your detailed response Mike, you're the first person to really provide me with an actual explanation!
