I recently used your carbon fibre skinning kit on a car product. I measured the resin to exactly 3:1 ratio in good conditions at the start of summer. 
The resin cured fine and I got it to a great finish. 

However 4 days after installing the product in the outside of the car the direct sunlight has caused the resin to form ripples in line with the carbon fibre. They are all equal straight lines. The resin has developed a greyish tone to it.

Can you explain why this has happened. I am working on two other car parts and I'm afraid to out them on the car in case the same thing happens.

Thanks
