It will basically restore the dryness of the plastic, turn the faded grayish appearance to be darkened and leave a layer of protection that will block the UV rays from fading it further. The restoration will vary from plastic to plastic material.
Here are the guidelines for split:
For split, I will need two people to reserve the split. One of them needs to ask for the original bottle and other in a rebottled bottle. Pricing is mentioned for both. I will then do the split (and will ensure the newer bottle is of very good quality).
As I type, @vague_one has reserved the "Original Bottle (with 6oz UTTG) -- 1700"
So I need one more person. Let me know if you're interested quick. You can even split it further with a friend on your own because if you are using this solely for the plastic trim, even 3oz (90ml) would last you very long for a few years.
