Painters always paint by body lines if there is not a body line for instance like this trunk lid then they will paint the whole lid to get it to match or to blend. Normally the side of a Car can be painted in sections since it has good blody lines.
IF a hood has a bad spot they always paint the whole hood right ? There you go this is a trunk lid same thing.
It will come back looking good PQ trust me.
I was told this by my personal painter.
