The carbon slicktop thread

Are see-through pinholes in carbon roofs or any carbon part expected?

Photos below are exterior shots with a flashlight inside pointed up at my carbon roof. I think nobody notices it because when it comes out of the shop, the headliner is installed.



I also see it on Vorsteiner bumpers:

Is that the inside or outside?

If inside then it might be a polyester core material peeling through. Not really an issue if it is on the inside.

if outside, some pinholes in an unfinished part is normal. Clear coating should fill in the pinholes. The part needs tk be sanded before spraying so the white dots could be dust stuck under the clear coat.

Which brand roof is this? Aren't these roofs supposed to be made from multiple layers to give it the strength that is required for a structural component?

I have seen light shining through the weave on non structural parts such as a CSL diffuser.

Here is the E92 CF roof production video:

The photos are from the outside. You can see the hole under the sun too.

I have the RKP roof I purchased from IND.


Here's a photo from the inside when sunny out:

That is odd. When I make my roofs I use a biaxial fabric under the exterior layer which takes care of any voids since the tows are 45 degrees from the outer layer. Then I use a thicker layer on the bottom.

Found this rare E46 M3 Vorsteiner carbon roof on the internet that seems interesting and wanted to share. Note that the underside looks like fabric. Is that the biaxial fabric you speak of?

Hard to tell from the pic. Looks like some sort of chop strand veil.
