More sloth lovelyness!!!

This one is a bit tricky to explain, but ill do my best.


When you anno aluminum, the layer of anno not only forms on the surface of the Aluminim but also grows into the metal.

To remove the old anno, they put your parts in an acid bath which eats away the anno. Once you have removed all the anno including the layer that has 'grown into' the metal, the part is smaller that it was when it was raw (not anno'd).

Putting on another layer of anno of the same thickness will increase the size of the part but not back to where it was.



This effect is very small, but when combined with other factors like the colour and therefore thickness of the anno, or how long the part gets left in the acid bath, it can become a problem.

But its very unlikely to have an effect.
