I'm sorry, can you rephrase your question? I do not understand what you are asking.

Cloth is great for larger flatter surfaces (but still curving a bit to keep strength). Unfortunately it is not strong in all directions if it is something more structural. Great for clean finishes. The Mat is great for strength since the fibers lay in all directions. However it does not make for as smooth a surface. If you want strength and smoothness, I use cloth for the surface and mat for the backside of it. You'll end up using less filler/build-up primer and allow for a more controlled surface. Another good benefit is that the mat on the backside disturbs the pressure waves and allows for cleaner sound (though MOST people can't hear the difference) For the majority of my projects, I use a polyester cloth base then use mat on the backside of it. If there is a large flat area I have to do, I use MDF and seal it later with carpenter's glue or Russian Birch Plywood. There's really no limit to how to do it really.

The difference between ordinary and extraordinary is that little extra.
