Hey guys!  I'm new to the forum, and new to composites in general.  My first project involved using a Red CF/Kevlar Fabric to hand lay up some side Moldings on my Jeep Grand Cherokee SRT8.  It took me a couple tries to figure out how to get it to stay tight on the part, and wait for the perfect time to lay down the cloth.  I finally got that down, and thought I was doing everything correctly.  Followed all instructions, advice, etc.  Anyway, after I got the finish perfectly smooth and scratch free, I looked at all four panels in the light and to my disgust, it was cloudy in the majority of places, with little white specks everywhere.  I don't know what I did wrong to get this cloudiness and specking.  It also looks like it goes all the way through to the CF weave.  I'm dumbfounded and don't even want to try again, if after all that hard work it's going to come out looking like this again.  I posted a picture of what I'm talking about.  It does not show the white specking, but you can see the cloudiness, especially towards the right.  And unfortunately this is not the worst one.  Any advice?
Thanks in advance,
Cody

Hi Cody and welcome.
Composites can be very frustrating at times. Assuming that you have wrapped the part not created it from a mould this is what I think may have happened but I would need more info from you to be sure.

Did you knock back the surface with wet n dry paper after the carbon was put down?
If you sand the surface too soon ie before the resin is fully cured and hard you can get this effect especially if you wet sand. I think the resin absorbs some moisture and if you then apply more resin/clear coat you can get the milky appearance. The white specks can be caused by the same thing.

Give it another go. I ended up with many parts in the scrap bin when I first started it is all part of the learning curve I'm affraid.

Regards Warren
