shut lines returns and flanges

What I'm really asking is are people happy with the fit and finish of body panels that rely on edging trim to get it through IVA and the general finish of the edges in general.
Has any body got comments about using black trim on the bonnet edges or any where else for that matter as to weather it looks naff or not? It would seem that it is acceptable to cover 7's and locosts in particular in black edge trim, this is to get around a lack of radius-radious in the edges of the moulds.
So do I bother to try and produce parts that do away with the need to cover every thing in trim or just accept that people are happy to do so.
