This is is developed to add a bit of aged tint to a pure maple neck. Each pass will slightly change your necks colour. It will not be a drastic change. If you look back through the history of fender guitars you will find a large percentage of their guitars had very natural aged necks even years later. This is designed to replicate that look. If you are looking for a much more amber colour you can make more passes with this to darken and deepen your necks colour. 1 can should be more than enough for a guitar neck.
The first headstock represents 1 pass of neck tint.
The second is of a raw maple neck.
The 3rd is multiple passes of neck tint.
This product gives you all the control to get whatever fender neck colour from whatever specific year you're after.
