Alright! Back at it and late with the update. So I didn't take any pictures of the visor being formed or detail shots but I'm sure everyone on these forums gets the gist or knows of a place where they can find similar gists.
Here is my fancy setup for the visor dyeing.

I forgot to mention a very handy tool for this process and a good guide for the vacuum forming, N8tebb's youtube.

This is the link to his visor video to which I used specifically for the dye process. I used his temperature and timing for my visor.
Heat was set to roughly 145F
Dye used was iDye Poly Black
Just the same as his visor in the video after 5 minutes in the dye and color enhancer I took the visor out and rinsed it in a bowl of lukewarm water. The visor looked good (I should've stopped there I feel like). I decided to let it sit another 5 as I could still see pretty good through the visor and thought it would be too transparent. After pulling it out after the 5 minutes I had rinsed again, wiped it down and let it sit. This is what we got.

In the pictures you could see that I had trimmed the visor and after dyeing any deep scratches or bumps in the plastic were more visible. I am unsure if this was due to heat as the pot got a little more hot than I had liked at one point, if I had scratched the sheet before working with it (likely) or if from material on the buck when vacuum forming. No matter the reason, I liked the "used" look of the visor, It seemed like it was actually used on a helmet and this had no change over the visibility. In one of the pictures you can see the visibility, it's clear and tinted well. In the light it does seem a little too dark but I'm sure it is because I haven't had much time wearing helmets with such a dark tint. Thankfully with such a dark tint when someone is behind the visor within the helmet you cannot see inside, so there is no need to chrome the interior of the visor to prevent anyone looking into the helmet.
