HD-Max repairs

All the great sales literature on the HD-Max states that it is the same color through the entire fiberglass so scratches are not seen. But, that is not the case as I have one 6 inch scratch that is much lighter color and sticks out.

So I would like to see if anyone has fixed scratches in their HD-Max fiberglass. Notice I stated fiberglass and not gelcoat.

When I called Thor, they told me since the color and shine is in the fiberglass when they make it, they do not gelcoat the fiberglass. They told me to use Sickens paint as a touch up and not to buff it like gelcoat. They told me to use Sikkens Auto OL-20. When I called a Sikkens dealer they told me there is no part number like that. I have went back and forth with Sikkens and Thor and cannot resolve. Looks like I need to have it color matched at a shop.

This is why I am asking if anyone has pulled out a scratch form a unit with HD-Max on it.

When you buy a Challenger, Thor includes bottles of touch up paint which I assume are Sikkens since the entire unit is Sikkens painted, at least according to the sales pitch.
