Chalk 140g

Chalk can be used for various things.
If the linseed oil putty feels sticky, you can add chalk. Knead properly so that it becomes a good consistency.

If you use putty slurry on your windows during maintenance, you remove the excess with the help of chalk.
Brush the chalk on the remains of the gruel and rub around the chalk and you will see that the greasy surface disappears.

Also works well to use if you are not going to paint on the putty, and the glass is oily after you putty.
Brush around the chalk on the glass until the greasy surface is gone.
