[MHml] fairing compound

[captnlen]

How are you applying it and what is the shape your working on

Having made a lot of molds and one offs the proper tool makes a difference.

I use the body shop spreaders and cut to the contour I am trying for if 
a radius or constant curve.

the toothed trowel is a good idea for thick buildup and get some pigment 
and add to each layer so you can see where the high and low spots are
