Hi there.

What you are noticing is what I refer to the 'velour effect'.

Let me explain;

Metallics contain aluminium flakes which reflect (or bounce) the light at different frequencies - hence why they glisten. Silvers have no 'real' colour apart from the flakes, so this phenomena is even more significant.

If the paint is applied differently than the paint surrounding it - the flakes are not in alignment, so the colour appears a different shade - much like running your fingers across a velour sofa - it looks different (but its all the same).

It can even be noticed if the robots in the factory spray left-right, and you paint right-left. This is why I only ever spray a complete bumper, rather than a cheap blow-in, there is no matching issues.

Can you post a pic of the damage? I may be able to advise a suitable technique. One thing to bear in mind is that touch-up paint is notorious for being too thick, so that in itself won't help the situation.


This job should never be complete - the day I think I've done it all, is the day I resign.
