Here is how laying 2x2 weave carbon works.
2x2 weave is very Sensitive.
If the weave move and we don't cover the back side with black or patch you are going to see right threw.And it will look like there are holes.
Because we only lay 1 layer of carbon on the top side.No point of layer 2 layer of carbon.
The black area" when pulling out from the mold,it has to be hand cut when carbon is harden.
And the black out area is going to be under your car that you can not see.
