Hi Seb,
Yes, the model would be that much lighter if you use Y2Klay. The amount of clay used would be the total volume, so basically it would take 2-3 boxes of clay at a guess of any of the Chavant industrial clays available.
Check their distributor list for a supplier closest to your location for the best price.
Below is a list of industrial clays available through the Chavant website.
If you have no luck, contact Chavant direct, they are very accommodating.
To retain detailed edges and sharp lines, it takes practice and will come automatically over time. On detail lines you can use masking tape to hold the edges crisp while you model up to the line. Also you can insert various thicknesses of fishing line along detail lines or around features to retain the edges.
Most of the hard styling clays are suitable for detailed work. If you are going to have super high definition then you may have to insert a separate piece into that section of the model. This is commonly done for head lamps and tail lamps. The lamp clusters are completed in a more suitable material then inserted as a separate piece.
As far as what scale to use, the smaller the scale the more you have to "cheat" to obtain a visually correct model. The smaller scales when increased to full size need more refinement due to the scale factor.
The trade off on a smaller scale model is that you are using less material and the model is that much lighter than a larger scale model. You also need less space for the project i.e. garage.

Hard Styling Clays (Standard)
CM-50: A "medium hard", dark brown formulation, considered the softest of the Hard Styling Clays.
J-525: A "hard" light brown formulation.
CM-70: An "extra hard" dark brown formulation.
Packaging

2 lb. Blocks 2¾" x 2¾" x 5" 50 Pounds
5 lb. Blocks (CM_70 only) 4½" x 4½" x 5½" 50 Pounds

Hard Styling Clays (DeAired)
These "extremely hard" formulations are the firmest of Chavant's Hard Styling Clays. Entrapped air is removed making the clay more dense, smoother and ideal for achieving fine extrusions.

DeAired CM-70
P-40: A SULFUR FREE. The hardest styling clay we produce that can be melted and poured. P-40 has a reduced working temperature requirement (115°). Higher wax concentration provides greater resistance to model cracks. Available in brown (natural color variations may exist in P-40).
I-307: Reduced sulfur content and reduced working temperature requirement (120°). Higher wax concentration provides greater resistance to model cracks. Hard but softer than I-305.
