Default Seibon CF trunk "clear coat" turned to CRAP!!!

my Seibon CF Trunk........





i am not happy! how can i pay $600-700 for something and then only two years latter this. not worth it at all! if anyone is looking at Seibon my advice is to keep looking! factor in that you will have to shell out around $300 on top of the price of the trunk to get the clear coat redone with one that will not turn into crap after only two summers. and yes i waxed my car every month and wash it once a week with good quality stuff and this still happen! thought Seibon was a quality product but i guess i was wrong!

Possibly. The issue is likely oxidation of the resin. See post #4

http://www.autogeekonline.net/forum/...iber-hood.html

You can try and buff out the oxidation. Without typing a book on the correct way to do this, I recommend doing lots of reading at the link posted above or finding someone local who knows what they are doing to help you out. This is not something you can do by hand by buying some rubbing compound.

Once corrected, you'll need to wax frequently with a quality wax or sealant to avoid it happening again.

Do you ever wax it at all?

I'm curious if getting a carbon fiber hood is even worth it, figuring I don't want results like this especially if one still takes care of it.

Why do they sell these products in the first place? I know they can make it better because I have better. I have a CF hood I've had for a couple years, bought it used even. I barely wash my car, barely wax my car, and the clear coat is perfect still. Apparently somebody can do it right, although I haven't the faintest clue what company made the hood, not Seibon, not VIS, something from China with no naming anywhere.

As far as worth, it goes two ways.

1) For older cars that still had steel everything, carbon fiber is the only way to lighten theses parts.
2) For newer cars with aluminum hoods, carbon fiber really isn't any lighter. I mean it can be, but the difference is small, especially comparing the difference from steel to aluminum and steel to CF. You're ending up near the same either way. The main gain with CF on the newer cars is more so an issue of durability. Aluminum on these newer cars is very thin and very easy to tend. By very easy I mean very, very, ridiculously easy. Carbon fiber can provide a similar weight option that gives you durability.

CF parts dont come with clear coat... but that happens because the resin doesn't have UV blockers, it is common knowledge that the resin oxidizes and that you should clear coat or tint (50% paint/50%clear) any wet CF that will see alot of sunlight its YOUR fault for not doing more research, just saying. luckily your trunk is salvageable with a little elbow grease you should be able to remove the oxidation and you can purchase resin online or even take it to a body shop to be clear coated

also to get something that size cleared would be about 100 bucks not 300 and you can buy UV blocking resin for 25-50 bucks online that's an even cheaper option, ALSO EVERYONE IVE TALKED TO HAS TOLD ME THAT YOU SHOULD NOT WAX CF parts or it will oxidize like yours did


YOU COULD ALSO RATTLE CAN CLEAR IT with clear from a parts store, that would cost about 30 bucks ($10 per can) another cheap and easy option, maybe if you did a satin clear it could have a DRY CF look?

I would expect companies to do it just because end consumers typically don't even think about such steps. If it's a bolt on piece for consumer use, it should be designed for such.

yeah but then you'd have people bitching it's "too expensive" when it's an extra $100

quick question though, don't mean to thread jack, but I got a CF trunk yesterday that has 4 holes in it from an S202 wing, and some little spider cracks around them...I'd like to take it to a shop and see what they can do but just curious if they can even fix stuff like that before I take it there. The cracks around the holes aren't deep, seem like just in the top layer of "clear" i guess you'd say.

Most of that will come out with a fine polish. But this kind of hazing is mostly caused by you not taking care of the product. You need to keep a few good coats of wax or sealant on any CF product at all times. Just like paint you can get UV damage but CF shows it much quicker as Seibon uses a mid grade UF protectant clear coat.

Sooo that's supposed to be a Seibon trunk.. That trunk definitely looks like it does not have a clear coat on it.. And Seibon claims everything they produce is clear coated... Someone is lying...

All of our products are made using one-piece carbon sheet, so you do not see broken lines and patterns. All of our products use clear coat finish. Clear coats are shiny and durable, and they give you the nice "wet" look as opposed to a duller look from gel coats. All of our carbon sheets are built into the mold, so they do not break and split like the ones where carbon is only wrapped around the skeleton.

WORDS OF WISDOM:

Any time you plan on purchasing something CF, always expect to pay extra to have a UV protectant clear coat applied. This holds true for 99% of any CF supplier.

As someone pointed out above, most companies do not apply a UV clear coat to their CF products and most of them do not use UV proctant resin in their products either. This has been covered since the 90s when CF became popular.


Also: If you plan on doing CF on your car, it's always good to make friends with a paintshop LOL

Yes, take it to a reputable bodyshop and let them fine sand the cracks out and reapply a UV clear coat.

If you want the holes plugged, they could do it, but it would be very pricey and you may not have a matching weave.

my Seibon trunk did the same thing after 4 years or so. I would wax it a few times per year and I parked in the garage at home. My Mine's replica CF lip did the same thing, so a friend and I two toned both pieces. Top painted (where the resin oxidized) and rear recleared.

here are the parts before spraying the clear.

unpainted carbon parts are pretty played out anyhow. its not like they save you much weight. nothing says dudebro street racer more then carbon trunks and hoods.
