I started off with the yellow version and it was looking amazing, then I made a mistake and had to change it and the colour as I only had one version of the stipe to go over the car, so went silver which is not that bad. 

On a model building forum, someone had brought up the use of clear LCD screen adhesive tape that is used for attaching phone and tablet screens. A search of Amazon brought up the item in different widths, so I ordered a 1mm and a 2mm rolls of the tape. It was a little tricky at first getting strips of the tape from its backing due to how thin the tape is. But once I figured that out, it was then just a matter of placing the tape in the body's frame opening, and placing the clear part in place and applying just enough pressure to get the part and the tape to contact each other, and hold the part in place. Once nice thing is if you need to adjust the part, you don't have any glue residue you have to deal with.

This post is to document the method I used to correct the problem with the clear headlight covers for my Ferrari 812 Competizione that were deformed. The pictures shown are the before and after of the pieces. As shown in the before pictures, there is a very noticeable gap between the cover and the body. Rather than using my heat gun, which would risk causing the rest of the covers to lose their shape, I used a small dish with warm water. It was just warm, not hot, so that it would allow me to gradually work the problem areas back into shape. Since the problem was the ends of the covers, just that part of the cover was dipped into the water and held in the water for a short period of time. I would then remove it from the water and gently massage that section in order to get it back into the proper shape. It was a little tedious, but to me, was the safest method to protect the rest of the part. After each dip and massage, I would then test fit the piece to check my progress. Eventually I was able to get both covers back into near perfect shape, and was able to install them on the body. The key is not to get the water too hot, and to take your time. This was the first time I had ever tried this process, and I was very pleased with the result.
