Antique restoration involves a lot of different skills, there is far more involved for proper professional restoration than just a quick wax. Firstly you need cabinet making skills to understand how the furniture was made in the first place and also how to carry out any repairs. Veneering - most antiques especially the more decorative ones are veneered or have veneered panels, these would have been laid by hand using traditional methods, no heated veneer presses here. French polishing - this would need to include colouring and matching as well as being able to polish large areas by hand. Most people with a little knowledge would be able to French polish a small box or a stool, but a table top of a grand piano requires long learnt and practiced techniques.
