Tire sidewall scrap

I have recently purchased some Toyo MT's I am very happy with. Going through the drive through at my favorite fast food restraunt is always a tight navigation in my 1 ton chevy. Long story short I got a light scrape going about 1/5 the radius of my tire's sidewall. It is only a superficial scrape, no damage to tire.

I have looked around for some way to fix the scrape but have not had much success. I see have seen some products designed to help with this but I fear they will change the tint of the rubber and further take away from the appearance of my new tires. On my previous tires I was using black magic to keep them looking brand new but after you apply it once you must keep applying it or the tires get a dull shade to them, hence my apprehension about using any tire product designed to make it look "new".

I have tried simple soap and water and it did help minutely but the scrape is still easily visual from 10 feet away. Any help is greatly appreciated!

Vulcanising solution will help "stick" the tear, but it will change the appearance and will give it a shiny tint in some light.

we use it to repair punctures when using an internal repair or "mushroom" patch.
