and there my not be anybody in the world better equipped to answer it.

How hard is it to add material to a resin model? I've used Bondo and sheet aluminum for years working on 'pot metal' cars but have no experience at all with resin beyond removing and adding decals.

Any quick tips because at $100 I have no fear of tearing into this car if it looks like the only way to get one of 1965 Ken Miles cars.
