no one claimed seibon's quality is better. your emphasis on quality was an implied statement since post #2. it needs more care, but it will last if you do it right.

 

It's called reserved parking spaces with shade at work and double garage at home .

I have no problems with yellowing on mine as of yet, have had the pieces (front bumper, fog light surrounds, fender vents, rear diffuser)for over a year now, but I take good care of it. My brother takes good care of his hood and wing but still they're turning yellow. Fitment is hit and miss. The front bumper replacement fits great, the fog-light surrounds fit great (even thought they took three months to get here), the fender vents one fits great the other side fits like **** (but I made it look perfect), the rear diffuser has its flaws and small fitment issues but it fits perfect now. I knew this while buying this stuff, that's why I haven't bought a hood or anything else large.

 

i get to park under the freakin sun every day at work still no yellowing though...guess i should consider myself fortunate?

 

Um yeah, actually someone did. Sleestack, based on personal experience, has an opinion that Seibon > Rexpeed.

I've heard of people having their cf products, regardless of manufacturer, wet sanded and clear coated with a high UV protectant clear coat from their preferred paint shop and that it pretty much solves the yellowing issue. Much more expensive and much more of a hassle than just slapping the piece on and calling it a day, but it would help the peace of mind.

 

he claimed fitment, not material/yellowing. please don't imply your opinion.

and if you must know, i have rexpeed items too, and they do fit worse than seibon. material-wise, they're both wet-laid carbon. quality beyond fitment and weight is negligible. like you said, it comes down to a proper seal and slowing down oxidation. a good clear coat is one way to approach it, but if the clear coat is low quality, you'll still get the same result. there are many types of clear coats out there. some can withstand uv rays better than others. waxing it regularly is just another method to the same ends.

 

That is correct. I have not had the pieces long enough to comment on any kind of fading. The only thing I noticed was that between Seibon and Rexpeed, the Seibon product fit better and had the weight of what I usually expect from CF. The Rexpeed products were not bad, but I did have more fitment issues and the hood vents, scoop and fender vents were all significantly heavier than the OEM plastic pieces.

I will say however, that given what these various pieces cost, I would expect Do-luck to have the most refined product. The products from Seibon and Rexpeed are pretty cheap, so I was pretty happy with the products that were delivered.

I'm wondering if Seibon has improved the manufacturing process on these CF pieces for the Evo X since the X first came out?

 

If you go to a paint shop and explain what you're looking for, will they usually work with you and explain what's going to do the intended purpose or will they say yeah yeah and just clear coat it with whatever they normally use?

I mean of course if you personally know the guy at the shop or something he's going to give you what you want, but was just wondering if the whole UV protectant clear coat is a commonly known thing in automotive paints...

 

seibon weave is hit or miss (side note: anyone else make a replacement oem cf diffuser?). any cf part will eventually yellow and discolor if you don't care for it. some manufacturers use better/more uv blockers than others.

wax is a good solution but it's temporary which is why you need to do it every couple weeks or so. i'd recommend a good sealant with uv blockers. they last A LOT longer (months vs weeks) and acrylic based sealants are scratch resistant (within reason of course, if you back into something hard don't expect it to be fine, although i backed into a wooden telephone pole with my sealed bumper and no scratches on the paint FTW).

I use Klasse, it's great stuff (the germans make good stuff!) and on top of that you can wax over it after it cures for that extra shine. 18 hours to cure.

 

Factoring the additional costs of a body shop to prep and spray clear coat onto the CF part, makes it an even more expensive thing to do. Even though, Rexpeed and Seibon are "more" affordable than others, they still dont charge pennies either. For the money, these companies should have incorporated a better clear coat from the start..

 

anyone know where to get the evolution x badge for the trunk?

 

Remember that CF was not developed to be unfinished. In the racing application it is usually painted. Look at any Indycar, F1 car or the Lemans Prototypes they don't run around with CF components exposed. Or look at production cars with CF, it is rarely unpainted. CF was developed for its strength/weight properties, not durability in the sunlight.
