Touch up Kit for Rosso Corsa Fer 300

There is no "kit" available.

You can take your car to an automotive paint supply place and they have a sampling machine that they can lay on the car and measure the pigments needed to make a small touch-up bottle.

It would be great to get the "recipe" for Rosso Corsa for one of the major brands of automotive paint such as PPG.

Then again, there is always this option:

Well,

I think that having a sampling machine measuring your paint is a great solution indeed, when available.
For a start, we have at least five successive itterations of the "standard red" for our cars, each one slightly different in tone/hue:
"Rosso Chiaro" for the carbed cars (from Glidden Salchi) then "Rosso", "Rosso Corsa", "Rosso Corsa 300/6" and "Rosso Corsa 300/9" (from Glasurit).
Then, paint on 35 year old cars can change a lot in color/tone/hue according to exposition to the sun or to light, etc...
So having touch-up paint that has been matched to your car's exact color is certainly the best option.
Modern paints are not produced on the same principle than the single-stage paint of our cars...

Dr. Color chip works great for small chips and their Rosso Corsa 300 is pretty right on.

 

Isn't there a Toyota shade that matches well available at your FLAPS. Search for it.
