taking your time is good because at least there will be good fitting mould
don't want to rush it, but I appreciate Doo's need for a spoiler !
Its pretty good anyway, I don't think that any undulations would be noticable anyway. Its not like a door or bonnet where it would stick out like a sore thumb.
The guy who will make the mould makes large pannels anyway so I expect the quality to be A1.
